Hello all,

I've read a lot of posts about that and I had my service enging light come on about 2 weeks ago.

Twice in that 2 weeks, the car was misfiring....unmistakable.

I took it to autozone and they pulled a p1320 off of it, that was the only code.

He turned the light off and the car was and is running fine now for a few days.

The light has not come back on and the car is not misfiring...

My question is am I possibly damaging the car by not taking it in (the dealer said I should not have had the light turned off as they cannot properly diagnose it until it reappears) even though the car is not misfiring?

If it reappears, I might try and buy the parts and fix myself ($700 vs. $250, or something like that??)

Thanks

 

You may have already seen it, but I started a very similar thread last night and got a number of good responses: http://forums.maxima.org/showthread.php?t=257149

I called my local dealer and the dealer in Tampa from whence it came and the SA's both said the exact same thing. I'm paraphrasing of course, but they said "You're going to need to replace all of them. If the code for the misfiring cylinder isn't stored in the PCM, we don't know which coil is bad and we have no reliable means of testing them." Then they referred to their service bulletin which basically says to replace them all as their justification. I considered a trip to the dealer, but I suspected I'd pay 1.2 hours for them to tell me to replace them all.
