Engine Surges and Lo trac light comes on then goes

Engine Surges and Lo trac light comes on then car dies.
Had plugs/wires/throttle cable and computer replaced, this is what the mechanic did and said would run like off the show room. Now says it has electrical problem? Once I can get the car to stay running it runs fine?

    Fuel filter was changed/O2sensor and Map sensor was also replaced. Mechanic says is electrical problem. I think he is trying to stick it to me, not sure? By the way is a 95 Lumina Car not Cavalier, if that makes any difference. Will try the solutions you suggest and see if that works.

1.Intake air vacuum leak. Check all hoses and bolts for tightness. With the engine running, wiggle all hoses around and listen for a hiss. 2. Change fuel filter, check fuel pressure. 3. Faulty idle control system/sensor.

How do I reset the computer for a 2003 cheverlet caverler


Repair the antilock brake system first. That should stop the engine light from coming on. If you don't do the repair, no matter how many times you reset the computer, the engine light will come on. Run a diagnostic test to find out what else is wrong. You reset the computer by disconnecting both battery cables, touch them together for a few seconds then reinstall.

I just got my alternator fixed then i started having the ESC serv ice light come on, and the trac symbol comes up and the engine light flashes. and the power is reduced and it jerks when driving


its possible that the incorrect voltage regulator was fitted to the alternator during the repair. A low voltage or irregular voltage from the alternator can cause havoc with vehicle electronics

Control off traction the trac off button lights up that wont let me turn it on what might be the problem


The light comes on and goes off when you start the engine as a test. If the light comes back on, there is a problem and you need to get the body computer scanned for trouble codes. The traction control uses the engine and ABS braking system to work.

My check engine light doesn't come on but my check trac light comes on but goes off


No, your check trac light is used to monitor the traction control system. It is sensing an issue in the traction control system, which is pretty complex. There may be a code saved in the computer that a dealer could pull for you.

The trac off light goes on and the engine light is blinking


This is common, when ever the computer sees a fault it will turn the light on and shut down the trac, the trac cant operate correctly when engine is not running good, you will need to have the computer scanned for codes, whenever the engine light comes on the computer stores a code with the problem, a flashing light means it needs attention asap, this mean its misfiring like a bad plug or sparkplug wire, the flashing is because you can cause damage to converter in the exhaust system, many autopart stores will scan the codes for free, for example they may pull a code that says po301 cylinder 1 misfire, this would mean cylinder 1 is misfiring, this take about 5 min, to get the codes, they use a small hand held scanner that plug in inside the car under the dash to the diagnostic connector which comunicates with the computer, hope this is helpful.
