Welcome to AF jenee2005 !

Your thread has been moved to the Grand Prix section.

Sounds like its time for some new plugs & wires!
If the've been changed and it's still doing the same thing, check for more trouble codes.
Post them and we'll help you figure this out!

Well I would certainly revisit the old third wire with a misfire issue. Hmmm, sounds like part of a song.

Sounds like you ignored a problem & now it's damaging your catalytic converter.
