Did you check the spark gaps on the plugs? This could be causing your problem. Also check that all wires are snug and properly connected. To check the gaps on your plugs just take it to your local parts store and they should be able to help you out, most likely for free. 2 thoughts-assuming the plugs are the correct ones and gapped right and tight and crush rings installed right. How old are the wires? They may have been damaged during the change. The misfire will be detected by the computer. If it is po300 it is from multiple cylinders. If it is a particular cylinder such as the fifth cylinder the code would be po305. See the 5 and fifth cylinder relationship? You didn't state the engine size. BClear. Assuming it is a 3100 motor, they have a fair amount of injector problems that are fixed by a fuel injection cleaning from a professional garage.
