do you have those metal sleeves around the spark plug wire boot? if so, take them off. they do more harm than good in some cases.
03-13-2012
alright. start at the top. you got new plugs? what did you get?
03-13-2012
Some NGK plugs have screw on pieces where the plug wire makes contact. If you have screw job NGK's consider changing them. This was a pain to find when it happened to me.
What brand plug wires?
If all else fails, I've seen a bad ICM not fire one plug. Ensure that both coil towers are throwing spark. That would indicate a possible bad ICM if everything else is good.
Lastly.. have any plugs ever come out of the cylinder with any damage? .

well the plugs i got were autolites, wires were from autozone lifetime warranty and the metal sleeves are off, and the number 3 cyclinder one had no end like the small metal thing on the end was off but i wasnt sure it was like seeing i dropped it befor i could inspect it, and theres spark coming from the coil both sides, i took the plug out again after running it for a while and it seems good no damage

thats about how i feel

autozone wires are prolly ur problem. also if they are new try rerouting them. i mean from the coils then under the dogbone (not through the bone) and then to the cylinders. appparently the route of the stock wires were horrible lemme know if that works

its just number 3 cylinder
03-13-2012
Have you checked the number three fuel injector yet?
03-13-2012
no i havent how i check em?
03-13-2012
lmaoThat guy prolly needed the installer mod.
that reminds me. are you talking about duralast? cuz those arent the BEST but they arent bad either. ive had plenty of good experiences with them.To add, I use autozone wires on TONS of 3800's.

Swap the #1 and #3 injector on the fuel rail and see if the problem follows the injector to cylinder #1.

They are great wires, 30 bucks...lifetime warranty.

^^^^^^^^ Could try that or swapping coils to see if the miss fire changes cylinder number too.
I have never in my life seen fuel injector cleaner do a thing as far as having a misfire light on waste IMO.
Miracle in a bottles are 90% the time a joke.

wouldnt a clogged cat problem get worse under load as the cars trying to get rid off more exhaust rather than idleing nope doesnt seem like an exhaust problem to me either.
Missfire still makes me believe its in the ignition system..............
03-13-2012
She said it smelled funny, which is why I asked about the cat.
03-13-2012
Dude im not trying to argue with you so chillax,
If your actually driving its producing more exhaust than at idle and it was already stated that the car runs worse at idle so problems at a lower rpm rather than actually driving the car would make me highly doubt its anything to do with the exhaust.

btw a bad cat would likely cause RANDOM misfire across all the cylinders rather than just one trust me ive had a 02 with a bad cat and it was throwing egr codes too and it was getting super hot.
