Guy I'm having a problem with my 88 crx, when the car is cold eveything is fine, lets say I hit the gas all the way to 6000rpm, then the rpms drop right away, perfec!, but, this is not happening when car is warm, when the car is warm and you hit the gas all the way to 6000 rpm, it stays there at 6000 for a second, then the rpms start droping very slow, its is a pain.. to drive the car like this, it seems like I'm racing or something.

The car has been doing this for a while, I did the mpfi and nothing, could it be the map sensor?

Any ideas?
