i searched, but i couldn't find anything that was similar to my problem

first of all, my car runs and feels great, except on idle. while idling, the engine shakes quite a bit, and you can feel it in the car-through the shifter. on the other hand, driving itself feels smooth.

my spark plugs looks normal, nothing too burnt, nor white
i just replaced my spark plug wires, and inspected my cap and rotor.

i checked the ecm for any codes, but just got the ole' code 55

so my car shakes while idling, but once under load, runs beautifully. you can also hear very faint popping sounds through the exhaust on idle.

i thought id be getting a code 45 for leaky injectors, but i didn't. i ruled out engine/tranny mounts since it feels great once driving.

while its idling disconnect each injector. If it shakes more plug it back in and move to the next one. the one thats leaking will usually not change the idle in any way and thats the one you should replace

i did that, all injectors change the idle speed drastically once the harness is removed
