Default 06 Cobalt Problems

I have a '06 Cobalt LS 2.2L that is having problems. It has thrown some codes P0128 ECT Sensor Below Thermostat Regulating Temp
P0455 EVAP System Large Leak
P0496 EVAP Canister Purge System High Purge Flow
and a few P0300 Random Misfires

It also threw a TPS code (which I have replaced), Fuel Filter (replaced), Fuel Cap (replaced), the EVAP Canister has been replaced also. My husband has been under the rear of the car and inspected all the lines and fitting, plus the canister and all electrical. The Mass Airflow was replaced as well.

The large leak detected code is the only one that hasn't been solved (aside of the obvious misfire).

It is still misfiring and sputtering and when I push the gas it won't go fast at all. It will eventually get up to speed but it takes it forever. Also it is going through gas like crazy (no leaks anywhere I have checked EVERYWHERE). I am not sure what else to do. Also sometimes when it idles it is fine, and other times it idles so low it acts like it is going to die. Thanks in advance for any info and advice. - Jennifer

Default Re: 06 Cobalt Problems

For the P0128 have you done the following?
•Verify coolant strength & level
•Verify proper cooling fan operation (check if it's running more than it should).
•Verify proper engine coolant temperature (ECT) sensor operation, replace if necessary.
•Verify proper intake air temperature (IAT) sensor operation, replace if necessary.
•If the above items check out good, replace the thermostat

For the EVAP code P0496 read the link below and the suggested solutions
