Ok here is the senerio I was driving my car and I was pulling right out of second gear and going into third and my engine felt like it hit a revlimiter or something not saying that it did but it felt like that. Instantly the cars check engine like came on and and I pulled into my friends drive way the car went to 1500 rpm and stayed there which is not normal and my car was blowing black smoke out of the exaust. After observing the smoke and idle I concluded that it is not coolant getting past the gasket, I turned the car off and turned over agian everything went back to normal check engine light went off and car idle fine. I drove back to my apartment on the way didnt rev past 3500 parked checked oil made sure it was toped off and all other flued check fuel pr reg fine and everthing was normal. I went to start the car take it around the block hit about 5000rpm and same thing happened all over agian check engine light and black smoke restarted the car everything back to normal.. Please help

 

jump the ecu and pull the code, could be possible that you're throwing a code for the o2 sensor.

 

what about the a bad pcv valve I dont think it is the o2 sensor but maybe I will check it out anyother sugestions

 

my 2cents will be on hmm... map sensor or TPS make sure these two are hookedup properly.... but first pull the code man
