I talked to HPF and they said use the powertrain coil packs instead of the bremi ones. So instead of changing the bad one, I bought 4 new powertrain coil packs and replaced the bremis. I now have 6 new coil packs. After I get done doing so, the car is still sputtering and shaking. After changing the coil packs are there any codes that have to be cleared or something else I was suppsoed to do that I didnt know about?

HPF also said check the gap on the spark plugs and make sure its .024. I will do that this afternoon, but if that doesnt fix it then what? I also ordered new plugs to see if thats the problem, but the HPF kit came with new plugs, so they shouldnt be old. Any input would help.
TIA
