Confused? hi i have a 1999 oldsmobile alero and it has the check engine light on. it is stuttering and i took it to auto advance and they did a diagnostic and said probably the spark plugs. that does make any sense or could it be something else?

    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

It is probably throwing a "cylinder misfire" code which is an indicator that the fuel didnt burn out of that cylinder, just change spark plugs, that is about the cheapest code it could throw, dont be alarmed.

I have 1999 Oldsmobile alero. Tracoff light and service engine on. Took it to auto zone code default said injector 3 misfiring cleaned all injectors still runs rough and lights are on . is there anyway to...


I doubt the problem is anything connected to the ABS.
Depending on the actual code, cylinder 3 could be a spark plug or coil problem, or compression problem. If the check engine light comes on, the trac off does too.

I have a 2000 oldsmobile alero, the check engine light is on. advanced auto said its a po105 problem, what does this mean


P0105 - MAP Sensor Circuit Insufficient Activity.If it is the 3.4 or 3.1L engine The Map sensor is located towards the back of the engine by the coil packs.Would verify that it is plugged in and also that the vaccum line going to it is not cracked,If all this checks ok then map sensor may need replaced.

1999 Alero stalling and trac off light coming on


does the rpm motor kick down? you may need to check your vacuum hoses, and also you may want to check your exaust, sounds wierd but that can cause the car to stall at times.as for the traction light, your hitting the brakes to hard. try slowing down a little slower while stopping, and keep distance for saftey.. if you can take it a little slower at lights and turns, without braking hard and it stops stalling.

I have a car in the shop right now same thing - it is being caused by a misfire. Need a real technition to diagnose the problem (auto zone - advance auto can't diagnose the problem - only read the code)
mine was caused by a failing fuel injector. good luck
