Random rough idle
Hey guys, I'm randomly pulling a cylinder 3 misfire code and my car idles rough when there's a load on the electrical system. I've done plugs, new battery, have new grounds on the engine but it's still running funny when i turn my lights on or i roll my windows up or down. I've rotated the coil packs to a different location to see if the code follows it but anyone have ideas of what else could be causing this? Alternator? I'm out of ideas. I was going to just buy a new coil pack but figured i'd see what swapping it out does first.
