Lack of accelaration, misfires after spark plug change.
Hi guys,
I recently changed the spark plugs of my 2005 350z. Nothing was wrong with them or the car, I was replacing the valve cover gasket and decided to replace the spark plugs while there. Upon starup,I am experiencing lack of acceleration, misfires. I ended up putting the old spark plugs back but the problem remains. Scanned the car: got a misfire error from cylinder 6. I replaced the coil from cylinder 6, issue remains. can anybody suggest what else to look for? Thank you! |
I would be suspicious of the possibility that something happened when you replaced the valve cover gasket. I wonder if you don’t have a vacuum leak somewhere; but, without seeing the car, I am only guessing

Some people get the wires crossed on driver side bank for Pistons 4 and 6. I've try switching those
I actually marked mine with white marker and if you disconnected the throttle body you have to do a TB relearn |
The wires were crossed from pistons 2 and 4. That resolved the issue.
Thanks for your help. |
