my aveo 2010lt has had ongoing ignition misses over the last few years and within the last few days its cropped up once more. OBD says miss in the #1 cylinder, whats the best plug to use since ive hear 100 different options, whats everyone using and why?
AC Delco copper or any brand plain jane copper plugs. Not iridium, not Platinum, not split fire. I heard iridium may work but copper is the way to go with these engines and stay as far away from Platinums as possible. It will run like crap with those plugs I can promise you that. It's because of the temperature and distance of the spark why it's best to use copper for these engines. What are you using now with it?Quote:

i use ngk iridium plugs. got them cause i hear they last a lot longer than copper although the latter is a better conductor.
maybe change the coil and plug wires too?
