Took my buddy and his shop's computer out for a drive today to see what my issue with misfiring is. We found that the MAP sensor had positive data readings... I unplugged it completely and the car ran exactly the same.
Now I know what you're going to say: replace the sensor. I already got that part. My question is why would it read positive? I'm not blowing $300 on a new sensor if it's a wiring issue left over from my tranny swap. Doesn't this system also have to do with the TCM in 4EATs?
