Hi,

I've been fighting a problem with our TR4A for a couple of years and it just
won't go away.  Symptom is a "sputtering" at high-way speeds.  Performance
seems fine - it just becomes no fun on longer trips.  Our annual fall sojourn
to Stowe is coming up and I'm looking for ideas.  So far:
*       replaced defective stainless steel muffler that had incomplete welds
on the intake - lifetime warranty honoured by TRF - thanks guys!
*       fixed problem with coil to distributor wire which was not fully "home"
in distributor resulting in pin making poor contact - checked all other plug
wires at pins - ok
*       installed NEW plug wires (yellow/black) and distributor cap
*       perhaps unrelated, but replaced fuel pump that went bad 2 years ago in
Stowe - replacement was Moss reproduction
Any thoughts?

Cheers,

Brian
