Lancer 2003 idles at 4000rmp
Upon starting the car the engine will race to 4000 rpms. Placing the car in drive it will go down to 1500 - 2500 but the vehicle will gradually accelerate to 50 mph without touching the accelerator. I replaced the MAF but that didn't fix the problem. I cleaned the IACV but that didn't solve the problem either.
