P0302 - Cylinder 2 Misfire Detected,what needs to be done.

SOURCE: didn't pass smog

did it fail high hc? you could change 4and 6 coils around and see if you get a p0306 that means the coil pack is bad. common on this type.

SOURCE: failed smog check

po304 is just that #4 cyl has a problem could be a bad spark plug or a bad plug wire or bolth
if it hasnt had an ign tuneup its time.
the po138 is just telling you one of the cylinders isnt burning all the fuel put into that cyl.
so its just cause and effect.
if ya need any more info let me know
later paul

SOURCE: never fixed a problem in a car before help..... i

first off check your spark plug wires. take them off one at a time and look for cracks or white burn marks. if they look fine check your spark plugs(make sure they are gapped correctly) and clean. if not either of those problems you will need to check the coil pack and ignition module. you may want to have someone with experience do this but if you want me to i can tell you how to ohm them and make sure they are functioning properly.

P0302 is a mechanical fault code meaning there could be a problem with the wiring or ignition/fuel system, could be a bad injector or ECT/MAF sensor or the ECM. (ECT=engine coolant temperature sensor)(MAF=Air flow sensor)(ECM=Engine control Module)
