1995 Dodge Caravan surges when you go over 50 miles per hour as if not getting enough power. Reduce speed back to 50mph and it drives fine. Cranks fine, drives smooth until you go over 50 mph I am perplexed
This is difficult because the computer can*t detect a problem, your vehicle thinks everything is ok. In reality what is happening is the electrical component inside the MAF sensor becomes contaminated by the impurities in the air. These containment*s embed themselves to electrical component that senses the air flow causing the sensor to be slightly off, but not enough to trigger the MIL (malfunction indicator lamp). Replace the MAF sensor with a new sensor and you*re problem should go away, plus your car get better mileage and performance. (Mass Air Flow MAF sensor or Air Intake Sensor AIS, depending on manufacture. It does the same thing with different names).
