MAP Sensor Issue and Solution

Check engine light kept coming on without any noticeable change in performance. Code pointed to a MAP sensor. I had a tough time finding a Motorcraft part to actually buy so I used a Carquest brand. Truck ran fine with the Carquest up to highway speed and then ran like it had a
governor at 70. Unplugged the sensor and was back to full power. So back to an original Motoracraft MAP sensor when I can buy one.

check your MAP lines for leaks and that the connecter when wiggled doesnt change anything.

These are now antiques and after 25 years, things get corroded and or worn out over time.
