A friend of mine just did a very clean 89 afm twincoil 4agze swap in a 91 ee-90 corolla. Now the only apparent problem is the the rpm readings are incorrect, seems as if its reading in half, and because of the the engine check light is constantly on cause the car to stall allot... We tried a new Knock Sensor same problems ??
Any Ideas.
