I have a 1991 chevrolet lumina apv which was recently retuned but the problem I am having is that when the MAP sensor is replaced it starts idling rough but when removed it idles fine. Yesterday, I replaced the MAP sensor. It won't start with the MAP sensor in place, so I removed the MAP sensor and started the car and it started allowed it to warm up before reving the engine twice. Then drove it for about 20km journey only for the engine to stop at about 16km and tried to start it again but won't start until I removed the MAP sensor and completed the remaining 4km and drove the 20km journey back home. To my surprise the engine didn't go off and ran fast but seems to be losing a little power when on about 130km/h speed. What could be the problem and how do I solve it?
have the same problem?
