Today I was driving and experienced my first coilpack going out, flashing CEL etc. I replaced the one that I thought was causing the trouble with a spare I had. Upon starting up the car I realized there was more than one and did the coil pack removal test to come to the conclusion that i needed one more. I went to the dealer and snagged one and proceeded to install it. I started it up and it idled and revved fine for the first little bit but upon driving it it started to misfire more and more. My thoughts are that removing all the coilpacks with the engine idling may have idled one or more of the spark plugs. Of course it could be the remaining two coil packs that I havent replaced yet. Does anyone have any thoughts or anything else I may have overlooked that could be causing the problem?
Thanks very much for any replies
