Engine Performance problem
2003 Pontiac Bonneville 6 cyl Two Wheel Drive Automatic 35000 miles
I have a ssei that is all of a sudden having the boost sensor fluttering and acts up more after the car has really heated up. The majority of time the boost sensor reads in the negative zone, but under acceleration the boost values will go over 0 to the positive side of the gauge. During the moments of fluttering, the sensor will go all from near red line of overboost to max negative and back. The engine rpm is affected enough that the engine will die at a stop, but the engine always restarts. It seems to really act up after the car has been operated awhile and really hot. The local repair shop has replaced the boost solenoid, but the problem continues. Any thoughts or actions would be appreciated.
have the same problem?
