OK here goes. After a warm up of about 5 min. I have no power. In other words when you give it gas it won't give you that extra power. Sputters and revsstay low. Idles fine, well ok. Have changed MAF sensor, new plugs, removed 1st set of O2 sensors to relive pressure in cat convertor to see if cat was plugged, no change but still not convinced I don't have a plugged convertor....there are 3 right? There seemed to be enough volume coming out of the tail pipes. Engine light does not come on but does work. It would seem I get a good reading from MAF but info coming out of ECM is distorted (computer). The fuel pressure was ok, was within limits. Disconnected coolant temp sensor and no change plus engine light didn't come on. Enough for now......any ideas???

 

Could be O2 however we did remove them...then the engine light came on plus there was no change in the problem.....not sure if that makes any sense also there was no code for a sensor problem.

 

Thanks for the replies.....I had a no start problem once and it was the crank sensor. Is it true that a faulty crank sensor could cause this loss of power as well. The interesting part is that when the engine is cold I can accelerate no problem......however after warm up the no power situation occurs.
