Car shaking like crazy under acceleration, no cel, what is it?
I have done a new fuel filter and egr canister for the hell of it, new throttle postion sensor, but car still running like crap. anywhere between 20-25 mph car starts to buck and shake uncontrollably under acceleration, but in neutral sounds smooth. I have no check engine lights, so apparently sensors are good. fuel pump doesnt make sense considering car starts and drives. anyone have this or similar issue? thanks!!!
