Cylinder 5 misfire 2001 Mustang GT

conate · 11-21-2004, 10:54 AM

Scanned my GT an received a "Cylinder 5 misfire" code on my ODBII scanner. Cleared the code and it came back agian 2 days later. The car is running/idling rougher than normal but still has plenty of power.Doesn't seem to be smoking more than usual at startup. Please advise if anyone has had this issue.

What mods do you have?

None.... the engine is stock

OK, I would definately pull #5 coil pack and spark plug. I would bet that you have a bad plug or a corroded coil wire or a bad coil pack. Easy thing to check. Sorry though, as I don't know which one is number 5. I forget how they are numbered. I am sure someone can help. Most likely you will know as soon as you pull it out.

Absolutely the spark plug, make sure you put Platinum back in if you're a stocker. Autolite is cool. If one is bad, can the other 7 be far behind? Time for a tune up, change them all. #5 is driver's side front.

Heck, if that's the driver side front, that is the easy one to pull. I take that one out all the time just to see how it looks. Just pulled it today.

Other than the back 2, none of them should be too terrible bad to get out. (A 4.6/5.4 in a truck, now that's a different story! LOL) Coil packs will sneak out from under the fuel rail without taking it loose. Just be careful with those things. If you break one though, AZ and Advance have them in stock. If you have #5 out all the time, check the coil pack boot real good, make sure something didn't get broken. Also, a littel high temp never seize goes a loooooong way on those.

Good Luck!
