Hey everyone! I'm a proud owner of 2002 Ls V8... Used of course, LoL! I am need of some help. Couple of days ago my car started running like crap. It would sputter when I tried stepping on it and even at a stop on idle. Finally the check engine light came on. I had it read and it came up as a "P306" I think- which meant a bad 6th cyl. I was told that if it was a bad coil, then other codes would of popped up, so I only replaced all the spark splugs and reset the computer. The check engine light is gone but the problem still occurs. Before I go spending crazy money, can anyone tell me what I should do next?
