Need a little tech advice
Need a little tech advice Last friday I put in a post seeing if anyone had an extra coil pack laying around b/c #5 coil went out on me. Well I replaced it with one from GM and my SES light is still on and the car is still missing. HP Tuners says its code P0300-Engine misfire. I checked ALL of the plugs to make sure they're plugged in and all the other coils are firing. What else could be causing it to miss?
thanks

Do you have the harness on the right way? If you put the wrong harness on the wrong side they won't fire in the correct order. The cylinder # is labeled on the harness near the actual plug for each coil pack.
Just an idea

I bought the car in July w/118k on it and right away I did !EGR,!AIR(partially i have yet to remove just turned it off via HP TUNERS), plugs(NGK TR55), Msd 8.5 wires, lid, and K&N filter. Then I parked it for the winter in november. I pulled it out of hybernation in the beginning of Feb b/c of emissions test but I failed b/c the system was reset due to a dead battery. And just recently I have had problems with the idle. A few weeks ago I went to the store and it was fine but the next morning it would idle REALLY HIGH and just kept climbing so I unplugged the TPS sensor and it was fine. i bought a new sensor then parked the car for a week. This past friday I drove the car to work and it was fine but in the morning AGAIN on the way home it threw the code and was missing. I got home found out it was a bad coil replaced it and im still missing. I was on the highway when it started to miss though. I went maybe 10 miles like that.
Im just stumped I've checked all the plugs its getting spark from every coil.
