Update: Stumbling Fumbling 1998 3.1Monte-Carlo
1998 Monte-Carlo 125,000mi.
Just wanted to give an update. I tested the MAF, cleaned EGR passage (carbon clogged). Pulled the spark plugs and found one that seemed to have the ceramic fractured. Replace it, and the car ran better, went ahead and replaced the plug wires. Car runs better, doesn't have the bad stumble it had before.
What I'm noticing now is the car runs fantastic when it's cold, but as soon as the car is warmed up it doesn't seem to have alot of power until I floor it. Then away we go.
I'm thinking something is going that's temperature related.
My mechanic friend hasn't been able to bring the scan tool over yet.
I still don't get any codes.
Would the local auto-parts store that offers free scans be able see anything?
Anyway, that's what's going on now..I'll keep you posted.
