Thread: 1997 Nissan Pickup Missfire

ted dehaan,

I think your right with the 02 sensor. My wife's 99 Cavalier was running bad would stall at a stop. When you had it going you could punch it and it would respond but low rpm would die. I changed the fuel filter, put injector cleaner in but the 02 did the trick.

To make things more complex i replaced the fuel filter and swapped the plug and injector from cylinder 4 to different cylinders to see if the missfire would move. Then i had a guy scan and clear the codes and now the service engine soon light wont come on for anything but a bad catalytic. Another weird thing it will only missfire if a mash the gas. If i ease in it seems to be fine. I set the cruise and cruised for a while and increased the speed one mph or one click at a time. Then i hit the increase speed button 5 times, i started to speed up but then started missfiring again. I canceled the cruise eased into the gas and everything was fine again.

Yeah, did the same thing, replaced the oxygen sensor and the air filter as well. The guys at the shop didn't do a good job ha. Good luck.
