It could be one of around 20 different things. The first easy step in the diagnosis process is pulling the new plugs to see how they look.
Well plugs look just fine!
Have you scanned it for codes?
No. Do you consider it might show as a code?
How many miles are on the car. Might be time to replace the coil pack and/or battery

Take it to an auto parts store and ask them to scan it for codes. Any significant misfire should set a P03**, and there may be others as well. OBD codes will somethimes point to the specific problem causing the misfire. If the codes aren't helpful, you can then either continue diagnosing, or start hanging on more parts if you prefer that approach instead.
So, i scanned for codes and it said spark wires (2-3 the mecanic verified) even tho i just changed them less than a moth ago I've also changed the sparks...well now my check engine light is off but its still misfiring. No clue what is going on!
Oh cleanned up the fuel inyectors too
What were the individual codes, in the order that they were read?Originally Posted by Micape30
