Power Cut off after warm up. Help.
Ok, this is hard to explain, lets say I warm the engine up and then take it for a ride, it drives fine when not beating on it, then lets say I want to go fast, It sounds like its hitting fuel cut off at low RPM, it skips and misfires as its climbing through the RPM's, it stops this after a longer time of driving, but it sounds as if i'm not getting spark, not getting fuel, or the timing is off, which it shouldnt be since I never messed with it yet.
if anyone knows what could be causing this, let me know. thanks.

It never did this before, just started happening with the colder weather coming and going.

All these things minus the fuel filter were checked, I just replaced the cap with a new one.
Its still wierd that it does this only when the car warms up a bit, when its been running for a longer time it dosnt do it anymore.

so.. what you're saying is it rungs fine until you give it WOT and then it starts to stumble and misfire?
what if you slowly increase the throttle position and get the revs up?
lets think about what happens @ wot, what changes.
1. the ecu ignores the o2 sensor and uses hard coded maps.
2. the low / 0 vac causes the fpr to up the fuel pressure.
check the vac line to the fpr ?
