Another misfire thread! I've searched and found some helpful info, but I wanted to throw a question out there.
My daily driven 140K mile '97 Cobra (stock minus an O/R x-pipe and mufflers), just started with a misfire today. I drove it all day yesterday without issue. I started it this morning, and moved it into the garage which took all of 30 seconds and ran fine.........then I come back out an hour later and it sounds like a cylinder is misfiring. All of a sudden sort of thing. Never had an issue till today.
Tune up was about 4 months ago.
New fuel filter, air filter, plugs (Autolite coppers properly gapped), and some parts store brand wires. I pulled the plugs today, all look great.
Odd thing is I'm getting NO codes at all (wish it would throw something so I could check). I drove it around the block and it misses under load. Idles a little lower than normal as well....almost to the point where it might die.
Suggestions appreciated. I'm a pushrod guy, not as knowledgeable with the mod motors. ...but I'm learning!
