WOT problem

may have an o2 sensor issue. Its in open loop (not adjusting fuel trim from o2 data) when its cold and when it warms up it goes into closed loop and reads the sensors. If your o2 sensors are reading incorrectly due to a bad sensor or a wiring issue then it could be leaning it out when you go under a load causing a loss of power.

I was thinkin that might be the issue too, its in a 92 s10, and the shorty headers have the 02 bungs right after the collectors. Would relocating the 02's make a difference? Where should the 02's be?
What kind of 02's are good ones? They have to be the flat 4 pin ones (female connectors)

Most of the time when a cat is partially stopped up you will notice a hugh loss in power after the cat heats up. Did this just start? I dont think your 02 location is the problem. Do you have a scanner?

Ok you can scratch everything said about the cats. You are going to have to get a hold of a scantool not a coder reader 2 totally different things. You are going to have to monitor what is going on in the pcm.
