I had a check engine light come on with code P1320 random intermittent misfire. Occasionally the car would run really rough for 10-20 seconds but otherwise seem to run normal. I did some research and found that this year model maxima is notorious for the coils going bad, nissan even issued a technical bulletin about it. The bulletin is not that helpful inspect harness / replace all coils. Well I replaced all 6 coils and sparkplugs, the car runs better it doesn't run rough but the check engine light continues to come on with the same code. I also inspected the harness per tech bulletin and could not find a broken wire, from what I can tell there is only 7 wires to inspect, one for ecm ground and six others - one for each cylinder but if a wire was broken wouldn't I get a more specific code such as misfire cylinder #4 etc.
I'm at the end of my rope on this one and need someone that's been down this road to help me out.
I don't want to keep throwing parts at it and i'm afraid if I take it to a shop that's all they'll do too running up a huge repair bill. I've already spent close to $500. I'll gladly make a donation to the cause if the info I get resolves my problem
have the same problem?
