Pontiac Bonneville Problem Report
Pontiac Bonneville Engine Stalling Due to Mass Air Flow/Crankshift Position Sensor Failure
intermittently stalling and engine RPMs revving up - Visitor
Stalling while driving, not restarting or will restart but then dies within minutes. Surges forward and RPM needle jumps all over the place. Have spent more than car is worth and replaced every sensor Known to mankind yet problem still persists. - Visitor
Random stalling was resolved by replacing the Mass Air Flow Sensor. - Visitor
Engine stalling intermittly. Change fuel filter and installed new plugs/wires. No change. - Visitor
car surges when n idle or at a stop light acts like it wants to cut off but doesnt already had the ignition replaced no solution for problem - Visitor
Stalling when you least expect it!! Replaced MAF etc - Crank Shaft Position Sensor is next. - Visitor
Car was fine and then it wouldn't stay running one morning. Disconnected MAF to let car run speed density mode and it ran. replace MAF and no further problems. - Visitor
Stalls Intermittently, as if the key were taken out of the Ignition. No Consistent Condition leading to stall. - Visitor
Reluctant to start but turns over great, stalls intermittently, idles higher RPM than normal and surges when accelerating. Pulled the MAF sensor connection and everything evened out. Planning to replace very soon...... - Visitor
Engine just stalls and replaced sensor and now it revs up on its own. - Visitor
Engine stalled intermittently but then could go more than a day without a problem. My mechanic said when he tapped on the mass airflow sensor with the back of a screwdriver, the engine would sputter, so it seemed likely to be the problem. He replaced it, and there have been no stalling problems since then (2 months ago). - Visitor
Car sat for roughly a year had the engine rebuilt, oil changed and the mass MAF cleaned out. It ran for a solid hour driving no problems, now when you start it you can see the psi creep up causing the car to stall with in seconds. Tried replacing the supercharge control boost silnoid and it made no difference. help!? - Visitor
engine would start up and run fine till temp reached 200 degrees then it would run rough and stall and would not start back - Visitor
First one sensor went then the other about 6 months later... not that both are replaced no issues anymore. - Visitor
Random rough starts when cold, normal starts when warm. Momentarily stalls at random engine ram's, never actually dies, just happens super fast, similar to shutting the key off for a couple of milliseconds. - Visitor
I've had to replace the MAF twice within 2.5 years, and I'm having the same problem for a third time. 1. The car will occasionally die while driving (between 25-45 mph) 2. It usually starts fine, but there are times when it takes several attempts to start it and keep it running. Worsens over time, and eventually have to replace MAF...again. - Visitor
check engine light been on for 7 months- stalls out more often than not lately, hard to get it going again - Visitor
Not starting - Visitor
Car started running rough and engine light came on. The code said to replace the Mass Air Flow Sensor. - Visitor
