i'v'e had rough idle issues ~ when car is warmed up - i was told that it was a bad coil. and then i replaced the engine (head gaskets blew) and more recently i am having rough idle as well...now it's rough idle even when on a cold start..?/ changed out half the ignition coils and i'm looking to do the other half tomorrow (hopefully).

i have no clue anymore at this point. if it's still bad when i change out the other side...i'm going to clean out the throttle body and IAC when it warms up a little more.

out of curiosity. what are symptoms of bad plugs?

i went to take out the ecu before to do the crush mod....and there was no bead to crush
