Why does my 4 cyl 1997 Grand Am hesitate to go when engine is warm?
Sputtering like it wants to stall and sometimes it does. Seems like more when stopping
and going around town. Service engine light was on. Replaced catalytic converter and
whole exhaust, 2 sensors. Waiting to see if the light stays off. I thought the replaced
exhaust would fix the problem. Replaced fuel filter about a year ago. Just replaced spark
plugs and it still hesitates when I give it gas. I have used the fuel injector cleaner but it
still acts up. Please help!
