Rough Idle & Studdering during acceleration
3.0 V6 Has a rough idle and bucks/studders under load and acceleration. I have replaced the fuel pump, spark plugs, cold start injector, EFI Temp sensor, Distributer, CAP & Rotor and no luck. It will start fine when cold, but has a hard start when warm. It back fires, bucks and has no power (more studdering) during acceleration. Any thoughts out there?
There is a recall to replace the head gaskets on that specific 3L V6. Google it for the number but I think it is 3V2 recall number due to poor gasket manufacturer. I had my 92 done and it works great now. L Lee Biloxi MS
