'97 GC hesitation...
my '97 GC frequently has a brief hesitation after restarting a warm engine.
(I6.) When cold, I never notice a hesitation at all. I can drive until it
reaches operating temp. If I restart the engine before it completely cools
down, it will hesitate some on the first acceleration. It will occasionally
have a very mild backfire or 'pop' sound, then accelerate normally and run
fine the rest of the drive. This has never happened when cold. It starts
fine (within a couple turns of the engine..) Any ideas?
thanks,
cal

Hi Cal,
Weak ignition wire or spark plug. It would show up instantly on an
oscilloscope. The unburned gas is ignited with the next firing cylinder.

Or coil. When my coil was going I got the same hesitation till it just
simply wouldn't start. (too bad they won't let folks just hit the coil
with a blast of freon to cool it off) :) That was an easy check.

Re: '97 GC hesitation...
A coil going bad for me acts like a rev limiter, I don't notice the
backfire, just lack of power.
