Ok so my engine bucks when its warm at idle.. feels like it wants to stall, but tach dosent really move, it almost feels like a misfire, but it isnt. so im thinking fuel system.. any suggestions on what to do? i was thinking fuel filter.. if not that maybe injectors?? any advice guys??

 

yeah mines been doing that lately too, just not to the extent where it feels like it will stall. I tried seafoam in the tank to no avail

 

I changed my Fuel Filter, no Help, and injector cleaner, nothing. I heard it could be my Spark Plugs, NGK TR-55 IX's, Cuz They Are Cold Plugs?? Or Because of my rear O2 sensors not being there..

 

rear o2s wont do that to you car other then maybe make it run a bit rich.....plugs can however greatly influence how your car runs....

 

My cars bucking too and I am running ngk tr55 with only 10k miles. If you find out the problem please pm me all this buking off idle is driving me crazy.
