Question about 1999 Oldsmobile Alero

1 Answer

Car keeps shutting off

I have a 1999 Olds Alero, 4cylinder and it keeps cutting off on me. When i'm idled or driving it. I've had a catalytic converter put on it and my spark plugs changed. I also had my fuel filter cleaned twice!!! And it still keeps shutting off on me. I even had my muffler replaced because there was so much build up in it. I took it to Firestone to have the spark plugs and fuel filter cleaned and another mechanic, which Firestone recommended, replaced the catalytic converter and muffler. I have spent over $1,000.00 so far trying to find out what is wrong with this car and it still keeps doing the same thing. My check engine light is on, my trac light is on and my gas hand keeps flucuating. Please if anybody can tell me what's wrong with my car I would really appreciate it. Thanks VP

    I have a 99' Alero 4cylinder, as well, has the same problem. Seems like everything is running perfect until your "trac off" light comes on then when you stop the car the engine studders and even cuts off completely sometimes. Cuts back on immediately yet the problem persists every so on. I usually cut the car off completely, start it back up and then it rides fine again.

Car keeps shutting off


I can solve part of your problem. I would check the crakshaft position sensor. These are located behind the harmonic balancer. This will caues the engine to shut off when the engine is at opperating temperature. As for your fluctuating fuel needle, I have a question for you. Do you use Shell gas at all? If you do then their detergents in the gas has eaten away at your fuel sending unit and it needs to be replaced. Only use Esso, PetroCanada (if you are in Canada) or Chevron gas if at all possible. Shell has had dealer bulletins about GM and Dodge not using their gas. The check engine light is usually a faulty O2 sensor but replace the CP sensor first.

1999 olds alero stall whe you take your foot off the gas and occasionaly wont start


hard start is AM is most commonly caused by a defective fuel pump pressure check valve, the other stall is issue is covered by the following procedure.
Here are some of the causes of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.
