Hello Mike

I had a similar situation in the BN3.

Tuned and reset everything multiple times and it just wouldn=E2=80=99t go a=
way.

After some weeks, eventually tracked the problem to the modern inline fuel =
filter that I had installed. Went back to how it left the Donald Healey Mot=
or Company and problem disappeared.

Subject: [Healeys] Austin Healey 100 Misfire Diagnosis.

This problem has plagued me for over 1000 miles.

Today I had to drive some 200 miles and this is how it went:

Starting from cold I experienced a persistent and irregular misfire. 

Pulling the choke out made no perceivable difference.

Power was not much affected and the car cruised along well in top overdrive=
 with just regular periods of misfiring.

Climbing slopes really made no difference, even when full throttle was appl=
ied for 10 - 15 seconds.

Misfire continued for some 90 miles with no change when the engine was full=
y heated up.

I could really do nothing to influence the rate of the misfire although it =
did seem to be slightly less evident at low throttle settings.

After 90 miles I stopped briefly to get fuel and upon starting off it was q=
uite evident that the misfire had disappeared almost completely and remaine=
d that way for at least 80 miles after which it started to misfire just a l=
ittle as I came to the end of the trip.

 POSSIBLE CAUSES

1.      Plugs =E2=80=A6 not like a bad plug. The misfire seems to be more t=
han 1 cylinder and never came close to being the regular beat that 1 plug m=
isfiring produces. All the plugs have a healthy brown/ grey appearance.

2.      Coil =E2=80=A6  In my experience coils are very reliable but when t=
hey do fail they tend to fail as they warm up and the problem gets worse as=
 the coil warms up

3.      Points =E2=80=A6 a possibility but the dwell is set at exactly 60 d=
egrees and does not waver at all when the engine is running in the shop.

4.      Fuel pump =E2=80=A6 if the engine was starving for fuel because of =
a fuel supply issue caused by a blockage or failing pump the problem would =
get worse when the demand for fuel increased, as in climbing a hill of full=
 throttle. This was absolutely not the case.

Any ideas folks?

The real mystery is why did it stop after you refuelled ?
Was there enough time for something hot to cool down - but that does not
really explain theinitial missing when cold.
Presume that you have given the cap and rotor a good visual ... tracking
can have weird effects.
Plug leads ?

I could really do nothing to influence the rate of themisfire although it d=

Mike,  my first thought was coil, as I have heard they can fail =
gradually.  For the small amount of work it is, I=E2=80=99d swap it out =
and see if it makes a difference if for no other reason than to =
eliminate that possibility.

=20

Starting from cold I experienced a persistent and irregular misfire.=20

Power was not much affected and the car cruised along well in top =
overdrive with just regular periods of misfiring.

Climbing slopes really made no difference, even when full throttle was =
applied for 10 - 15 seconds.

Misfire continued for some 90 miles with no change when the engine was =
fully heated up.

I could really do nothing to influence the rate of the misfire although =
it did seem to be slightly less evident at low throttle settings.

After 90 miles I stopped briefly to get fuel and upon starting off it =
was quite evident that the misfire had disappeared almost completely and =
remained that way for at least 80 miles after which it started to =
misfire just a little as I came to the end of the trip.

 POSSIBLE CAUSES

1.      Plugs =E2=80=A6 not like a bad plug. The misfire seems to be =
more than 1 cylinder and never came close to being the regular beat that =
1 plug misfiring produces. All the plugs have a healthy brown/ grey =
appearance.

2.      Coil =E2=80=A6  In my experience coils are very reliable but =
when they do fail they tend to fail as they warm up and the problem gets =
worse as the coil warms up

3.      Points =E2=80=A6 a possibility but the dwell is set at exactly =
60 degrees and does not waver at all when the engine is running in the =
shop.

4.      Fuel pump =E2=80=A6 if the engine was starving for fuel because =
of a fuel supply issue caused by a blockage or failing pump the problem =
would get worse when the demand for fuel increased, as in climbing a =
hill of full throttle. This was absolutely not the case.

Any ideas folks?

Hi Michael -

Have you tried cycling the connections on the white wire from the ignition
switch to the coil, and also from the coil to the distributor.

You might also want to try disconnecting the black and white wire at the
coil from the battery master switch - if it=E2=80=99s failing you=E2=80=99l=
l get weird
symptoms like this.  If that wire is disconnected the car should run no
problem.  I don=E2=80=99t recall if that wire is separate from the distribu=
tor
wire, if it isn=E2=80=99t you=E2=80=99ll have to disconnect it from underne=
ath the master
switch itself.

Best,

Alan

    It is (or should be). If the battery switch is in the 'OFF' position
    it grounds the coil primary so no spark.<br>

Michael -

Just as a follow up to my email since the symptoms seem to manifest
themself  ...

   - whether the car is warmed up or not - this typically will exclude
   anything related to fuel or the coil
   - whether the car is under load or not - this typically will exclude
   anything related to fuel
   - whether the choke is pulled or not - this typically will exclude
   anything related to fuel
   - somewhat intermittent but systematically under all conditions -
   suggests to me wiring / ground issues

Given this I'd check (as a priority):

   - Battery Master (when these fail they will ground the coil)
   - primary ignition wire (white) from the switch to coil (cycle the
   connections)
   - motor ground straps (cycle the connections)
   - loose wires in the dizzy
   - loose ignition wires into the dizzy or spark plug

Other things to possibly do (as secondary):

   - replace rotor
   - replace dizzy cap

I don't think it would be contacts or condensor simply because this would
either be very regular all the time, or maybe sensitive to temp.

Best,

Alan

Coils can fail with heat and then recover when cooled. I had one that had
these symptoms and when looking closely I saw that the insulating oil had
run out through a very small crack in the bottom of the case.

Hi John -

Yes, that was the point I was trying to make, sorry if it fell through bad
interpretation!  As Ed McMahon used to say, "You Are Correct Sir!"

Cheers,

Alan

Thanks to all who have obviously given this misfire issue considerable
thought. I will be sure to check all suggestions.
I  should like to point out however that it is the immediate vanishing of
the misfire after filling the fuel tank that has me confused.
This has happened three times simce the problem appeared.
I just don't understand how an ignition problem could change as a result of
filling the tank.
Furthermore I'm convinced that this is not a fuel starvation problem
because the amount of engine power being used has no effect.
Totally baffled.
Thanks again to all ... I'll  report back.

I suspect that when the tank is filled any sediment or debris around the ta=
nk intake is redistributed thru the fuel then it settles again.  Classic si=
gn of bad fuel filter or sediment in tank.

Subject: Re: [Healeys] Austin Healey 100 Misfire Diagnosis.

Thanks to all who have obviously given this misfire issue considerable thou=
ght. I will be sure to check all suggestions.
I  should like to point out however that it is the immediate vanishing of t=
he misfire after filling the fuel tank that has me confused.
This has happened three times simce the problem appeared.
I just don't understand how an ignition problem could change as a result of=
 filling the tank.
Furthermore I'm convinced that this is not a fuel starvation problem becaus=
e the amount of engine power being used has no effect.
Totally baffled.
Thanks again to all ... I'll  report back.

Hi John -

Yes, that was the point I was trying to make, sorry if it fell through bad =
interpretation!  As Ed McMahon used to say, "You Are Correct Sir!"

Cheers,

Alan

Coils can fail with heat and then recover when cooled. I had one that had t=
hese symptoms and when looking closely I saw that the insulating oil had ru=

  *   whether the car is warmed up or not - this typically will exclude any=

  *   whether the choke is pulled or not - this typically will exclude anyt=

Given this I'd check (as a priority):

  *   Battery Master (when these fail they will ground the coil)
  *   primary ignition wire (white) from the switch to coil (cycle the conn=
ections)
  *   motor ground straps (cycle the connections)
  *   loose wires in the dizzy
  *   loose ignition wires into the dizzy or spark plug
Other things to possibly do (as secondary):

  *   replace rotor
  *   replace dizzy cap
I don't think it would be contacts or condensor simply because this would e=
ither be very regular all the time, or maybe sensitive to temp.

Best,

Alan

It is (or should be). If the battery switch is in the 'OFF' position it gro=
unds the coil primary so no spark.

Have you tried cycling the connections on the white wire from the ignition =
switch to the coil, and also from the coil to the distributor.

You might also want to try disconnecting the black and white wire at the co=
il from the battery master switch - if it=92s failing you=92ll get weird sy=

How old are your plug wires?  Any chance a few worn out wires be the origin?=

I had a similar miss that was caused by a leaf that had gotten into the
tank.  It would be pulled against the pickup by fuel flow and cause the
engine to lose power on all cylinders, as opposed to a miss.  When I either
got off the gas pedal or shut the engine down the leaf would apparently
fall away from the pickup and everything would be fine until the leaf was
once again pulled against the pickup, etc. etc.

I empirically came up with this theory after I pulled the fuel sender,
searched around in the tank with a flashlight and found the leaf, and after
I removed it the miss went away.  How the leaf got into the tank when the
fuel filler is inside the boot is a larger issue I never figured out.

Good point.  I had a very similar experience when I had mistakenly used

BUT ... the fact that full throttle and climbing a slope with no change in =
the amount of misfiring tends to negate fuel blockage as a cause.
I'm starting to think that the refueling situation is something of a "red h=
erring" although it certainly is an odd one.

If the bits are floating around in the tank sometimes they are away from
the pick up, other times they are stuck on the pickup.  It acts like a
little flapper valve that can float loose from time to time, and finds its
way back to the pickup as fuel is being drawn to the engine.  Good to use
an endoscope and check the tank.

I'm still leaning toward bad battery master or bad wire connection
somewhere.  Also if lights are dim, clean the battery contacts.

So what is unique to a fuel stop besides the fuel?  Adding weight to the
boot area, opening the boot lid, removing the filler cap.  What else?

An unvented filler cap could restrict fuel flow.  Extra weight  and even
opening the boot lid could shift some recalcitrant ground or other
connection or loose shorted wire. Maybe even at the battery switch.
