Actually it's more of a cough and it is very minor. It is minor enough
that I don't get an engine warning light, and it passed my last state
emission check.

It only happens when in gear and stopped. If I place it in neutral or
park, or am driving, I don't feel it. Cold or warm (weather and engine
temperature) it's always the same.

I've:
replaced the fuel filter
replaced the plugs
replaced the plug wires
checked the timing
flushed the injectors

and none of those seemed to make any difference.

I've checked the history of the group and don't think I've seen anyone
else with a similiar problem.

Any ideas? Thx in advance.
