I have a 2000 Olds Alero 2-door Coupe, with only 86,000 miles on it now. The first time my engine stalled was about 5 months ago as I was turning from one country road onto another -- the engine just quit half-way through the turn. I rolled to the side of the road, and the engine re-started up right away. It was a very hot day, so I blamed the weather. The second time was about 2 1/2 months ago, and it was also hot. I had stopped at a stop sign, and it stalled when I started to take off. The third time was 5 weeks ago, and was similar. The 4th and 5th times were 3 days ago, and only 10 minutes apart -- the last was just as I was entering a roundabout (rotary) and as I accelerated, it just stalled and quit (which make the car driver behind me very angry). I took it to Thompson Chevrolet/Buick/GMC (Patterson, CA) where I bought the car used in 2002, with 20,000 miles on it already. It has always been a great little car for me, getting 30 MPG on highway trips. They worked on it for a few hours today, and found that the "engine hose to the MAP sensor had a hole in it". This Oldsmobile apparently had a Pontiac engine in it from the onset. Replacement of the hose, clean out of the area, repairs, and labor only cost me $147. Very happy that they found the cause easily, and that I didn't have an accident somewhere along the way in those 5 months. My "check your engine" light had gone on about 3 times during those 5 months, but it went off within a few days each time, so I ignored that. - Visitor
Check engine light came on. Codes PO105 & PO108. Replaced vacuum hose. - Visitor
