Engine stalls while driving .

[dandettman]

When I start to drive in wet weather, my Alero put puts in a jerking motion and the Check Engine Soon light starts flashing. After I drive for a few feet this stops and the light turns off. Any ideas on what is wrong with the engine or fuel pump?

The damp weather gives this problem away. What are you experiencing is a misfire condition do to an ignition component being wet, or damp with moisture. The check engine light will flash when the car is misfiring as well.

Usually this ends up being ignition wires that are bad, cracked, worn out, etc. It could also be an ignition coil. It's not too difficult to replace the ignition wires so you might want to start there, as that's the most common thing.

The engine stalls while driving. It don't give any warning, it just quits. But it will start right back up. Then it'll run a while then it will do it again. Any help would be appreciated. Thanks

This depends on which model Oldsmobile you have and what engine size. There are common things for different engines. For instance, on the 3800 engine, a crank position sensor is a common problem. They tend to fail when the engine gets hot. Then when it cools down a bit, it will start and run for a while longer. The 3.1L oir 3.4L engine is more common for a bad ignition control module going bad. With that said, any car can have a fuel pump act like the problem you are having.

You would need to find out what is missing when it stalls. Is the engine missing spark, fuel pressure or fuel injector pulse or a combination. That would give a battery indication as to what the problem is.

My checked engine light is on when I start my car or idle low. The rpm goes up and down until I drive it doesn't do it all the time but it gets worse. I took it to part store computer that aid something didn't give specifics and said maybe oxygen sensor or vacuun line fuel filter. Sometimes when it's less than a qt. tank of gas it would sputter up a hill. Like it was out of gas but didn't die. Almost did. When it has half tank its fine. But now it's just the idle goes real low almost dies but doesn't. RPM goes up and down to when put it in drive and go and it dies.

what did the parts store do? did they scan the vehicle. Is the check engine light on while you are driving? It may come on when you turn your key to ACC but once the engine starts the light should go out unless there are codes stored in the PCM. The parts store might scan it for you. Or take it to a shop and have it scanned. Just putting parts in because of a "maybe" is going to get expensive. Even if you have a code that says the engine is running lean or rich (associated with oxygen sensors) it could be that the oxygen sensors are reading perfectly and your engine is really running lean or rich. The code that is stored is a beginning point, not the answer (usually). you read the code. you look at what the code is pointing to and look at the parameters that can affect the code. (diagnostics) I can remember when fords would get a p0171 code and shops were replacing O2 sensors like crazy but the problem was a dirty MAF sensor. So, you have to look at what causes the code. What the code is. What the code is affected by.
