[QUOTE="hal keiner, post: 987017, member: 66101"] I am not one to throw parts at a problem instead of diagnosing the problem first, but I don't have the skill or equipment to test spark plugs, wires, or coils to see if they are defective. Plus for the effort to remove these parts, I am thinking I might as well replace them with a new part. Also, after 120K miles replacing the coil might qualify for routine maintenance. The fuller story is that I was getting a periodic/random P0303 (misfire on cylinder 3) code and stumble upon accelleration for many months. I replaced the plugs and wires and the P0303 stopped and the stumble almost went away, but not entirely. I have cleaned the PCV, MAF, and IAC and also checked that the famous 'elbow' was not leaking air. The coil pack is one of the last few ignition items to address. Since testing is not feasable I thought swapping out this part would be an easy and cheap thing to do to eliminate it as a possible problem. My thoughts anyway. However, if a coil pack can only either work fine or not work at all (rather than cause minor misfires, stumble, poor performance, etc.) then it is not worth replacing to see if it makes any difference. Have I got this right? [/QUOTE]
