I have read a few threads on this subject discussing the causes. In my case the car would run perfect until it reached operational temps. It would then stumble and jerk in light accelerating at anything under 2600 RPMs.

Fine I cleaned the MAF first. Nope

Then I changed both pre cat o2 sensors with SMP/STANDARD SG454 Oxygen Sensors. It stumbles even when cold now.

I only have had the chance to drive it one time so is this something the computer will have to learn with the new O2s or as I guess most will say you didn't get factory AC o2's so you are screwed?

I sure do not relish the idea of having to do this again and laying out more cash. Has anyone used these sensors?

Thanks.

If it runs good until it heats up, probably your ICM.
