ABS, traction control problems. Emissions and fuel related repairs.

2006 Chevy Cobalt. Is there any service bulletins on The 2.2 ECOTECH oil filter gasket being cut, if installed Improperly? The O ring gasket severed during install 2 weeks later ran out of oil causing a rod to throw, but the canister did not leak after the oil change?

Answer: If the large O ring were to be cut or roll during installation, you would have an external oil leak right away. The small O ring on the tip of the filter being damaged would cause an oil pressure problem.

I bought a 2006 Chevrolet Cobalt LT without a key, I got a key cut so I could get in the car, but It will not start the car do I have to take it to a dealership?

Try this procedure. If for some reason it does not work, then it will have to go to the dealer so they can use a scanner to re-learn the theft system. Expect to pay 1/2 hour labor for that.

2005 Chevy Cobalt 2.2 liter Automatic will not go into reverse. Drives forward great????

Ok, well nothing electrical can cause a no reverse condition. There is some sort of internal failure. Many things can cause this.
From the reverse clutch, to the low reverse band, or a servo piston, or stuck check valve, manual valve, etc.
