Question about 1999 Oldsmobile Alero
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 1999 Alero 4 cyclinder. Car cuts off at stop lights, going around turns, etc.
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.

Tell your mechanic to check the key ignition module.
