Asked by robedsquid apr 19, 2018 at 12:02 pm about the 1998 toyota corolla. The interesting thing is that if i disconnect the maf sensor the car runs smooth but idles around 3k rpms (very high). A way to test the maf theory before you go drop $90 on a new one is to simply unplug the maf sensor in the morning beofre you start the car.
