Im having a problem were my car shakes at low rpms when coming to a stop or when stopped it only vibrates from 2000 rpm to 1000 rpm then after is idles fine. The needle jumps in very little incriments almost cant tell but i can feel the shaking. Anyone have a resolution to this i have one step colder plugs gapped to .40 idk if this is a problem or not

bump

 

help me lol

 

Check the throttle body; it is probably really, really dirty.

 

how many miles? could it be the engine/trans mounts are worn?

 

48000 miles

the throttle bodyhas been cleaned before and my car didnt do this until i got 42's,2.9 and trifecta tune

 

my steering wheel shakes at HWY speeds, car doesn't feel solid anymore...pretty sure its the intermediate shaft bearing. Just need to get around to fixing it.

 

motor mounts and CABS

sounds like a bit of misfires too

 

could it be my 1 step colder plugs there gapped to .40

 

bump could this be a bad injector my car doesnt shake bad like it wants to stall its almost not noticeable to the passenger
