misfire when hot
ok i have been having this problem for a while now. the car runs fine but it misfires a little at idle.i have done a compression test and all the cylinders are up to specs. i have replaced the coil with a msd, new bosch wireset, new platinum plugs, accel cap and rotor, and set the base timing to spec, new injectors,cleaned iac and throttle body, new bosch o2, the car runs fine except for this little problem; i would like to fix this because it bugs me. what else should i test? the only thing that i haven't replaced is the ign. module but i had it checked 15 times at autozone and it passed every time. could this cause my problem? many thanks in advance
