[Fot] Missfire

[robertten1 at aol.com]

I swapped the plugs around to the cylinders that fire and those that don't.
The same two cylinders that fired fired and one and four nothing.  Yes there
is spark going to all the plugs, my getting a good jolt a couple times was
also confirmation.  I'm also looking into any vacuum leaks.

Thanks for the tip,
Bob T

Have you confirmed that the plugs aren't firing?  If not, remove them, clip on
the plug wires, and lay them on the engine so they'll be grounded and then
watch
for sparks jumping the gaps on all four while the engine is cranked over.
