Engine Performance problem
1989 Ford Bronco 6 cyl Four Wheel Drive Manual 149000 miles
4.9 ltr, NEW MAP sensor but have to unplug to get engine to run half way smooth. No error codes when hooked up to analyzer. Throttle position and most other sensor's replaced. Main computer swapped out with no change, also ICM. What else could it be?
