Old plugs were burnt and you got misfire right AFTER you changed them?!Before replacement everything was fine?!

I'd take the plugs and wires back and get you a set of bougicord wires and OEM plugs. FCP sells the kit and it will come with a lifetime warranty...

other plugs and wires are back at autozone but needed to get to work so bought the autolite copper 3923 plugs and used old bougicord wires

Is misfiring gone with old wires?

Misha, here is your answer from page one:

samtron6 wrote:well old wire are in and everything was fine till CEL on again..... now its random misfire,,,,, and misfire cylinder 2 and 4 instead of 2/4/5... plugs are gapped right wires are in the right spots... after CEL comes on it runs like crap for a few then runs fine till i sit at a long light then it tries to bogg down for a second when giving gas... never did this till i changed plugs ??????

Test the MAF, it's free (unplug it before starting the car, drive around).

I missed that post erikv11.

Bad Maf will not cause misfiring,you know that.
Check cap & rotor.

Remove it and visually check contacts inside of it for burnt traces or corossion.Or take a picture of contacts and post them here.
19hours....i would get myself a good sleep before doing anything.
