The problem I have is nothing new. When I start it up it revs to 3k rpms and then after a couple of seconds it drops down. But its very inconsistant. Sometimes it will go up to 2500 or 2000 rpms. What have I done. I replaced the tps and the IAC cleaned the throttle body real good even in the IAC spot. The Tps was calibrated but I only read 4.8v instead of 5v on A-B, smooth movement on B-C when I move the throttle. Mosty of the parts in the engine bay or new. Cps is fairly new. The only thing I didn't mess with is the FPR and the MAP sensor. If I unplug the MAP the car dies. I pulled the Vac line off the FPR but smell no strong gas or see any. This problem Im having is wierd cuz in the warm weather I can unplug the IAC and the car doesn't do this. But in the winter and the IAC unplugged the car idles very low to the point I need to gas it for several minutes till it will hold a good idle. There are 2 temp sensors I know of. One on the intake and another on the back of the head. The one on the head I know is used for the gauge. The other I remember replacing last year or so. But unplugging doesn't change the way the car runs. I need some help.
