    It does sound like your catalytic converter is done. To fix the problem, go to the dealership and ask to confirm that it is the cat. converter. If it is then I advise you to have the dealership to put in a non-after market part.

    It sounds like the coil pack or packs are weak. Is this a 4 or 6 cylinder? If the coils go, you will have no power and car will only chug. It could be bad wires or plugs too, but I'd start with the coil packs . Follow plug wires right back to the coils. There are 2 coil packs on those cars and it will probably only be one that is bad

You need to have the PCM scanned to check for stored codes. Even having symptoms without codes can indicate certain problems.

Chevy cobalt cranks but wont run above 10 mph


I doubt the security system would cause the problem.
Most systems prevent the starter from working as well as the fuel pump or injectors.
And once the starter cranks the engine it should not be involved.

Air intake temp sensor. Check the wiring to the sensor and make sure there are no bad places or hard kinks. If that doesn't change things replace the sensor.

Wont pick up speed


from the way you describe this, I am assuming this is an automatic transmission. Sounds like clutch packs are shot and the trans needs rebuilt or replaced.

Do you have less than 80K miles on the Escalade? Check out www.speedometersettlement.com if so. Mine started having issues at 56k & I'm expecting full reimbursement from the class action laqsuit.
