Re: cylinder 5 misfire
Hi Brenda, I just conquered a Number 4 Cylinder misfire trouble code. However I've been dealing with another code just before that. It was an O2 sensor that I had already replaced a couple of years ago, and therefore I didn't want to replace it again because I was thinking it might be one of the numerous other possibilities like a leaking fuel injector, low fuel pressure, leaking internal fuel pressure regulator, mass air flow sensor, and so on. After countless efforts to test and troubleshoot and eliminate I finally changed the darn O2 sensor and cleared the light by disconnecting the battery completely for a few minutes. The light will stay off if the problem is fixed or it will come back on after one drive cycle (about 10-15 Miles) if it is not fixed OR you might find a different code. It get's complicated when there's more than one thing wrong. My Number 4 cylinder misfire ended up being resolved after I replaced the plug wires and that one spark plug, since all the plugs had just been replaced a month and a half ago. The problem was that number 4 wire was not delivering enough spark due to insulation break down, that happens after a few years, and I have made the mistake of buying cheap wires, and will never do that again. Lifetime baby and save the receipt. I just got a free set. It is possible to get defective new parts. I have had to return a couple. Get your code read again and a print out at autozone of possibilities, research it like crazy, but just remember. Just because some idiot thinks he knows what he's talking about and posts it on the web doesn't necessarily make it so!
