hi everyone I promise I was going to post my check engine codes from a hummer I purchase. Im not sure on all the codes on this so I figure you guys might be able to help.

 

many of your codes look to be wiring related. check your engine and transmission harness for breaks also check the grounds. you also might not have a thermostat in the truck.

 

o ok im going to have to check the harness for any breaks then and get the cylinder fixed.

 

that also can be the wire harness going to that coil. you can swap the coil with one of the other ones and see if the cylinder 2 misfire moves to another cylinder. if it does then the coil needs to be replaced. if not then check the wire harness going to it and also it's spark plug.

 

thank you im going to try that

 

Ours had a P0128 so I ordered a new thermostat and coolant temp sensor along with new radiator hoses since they were cheap.

Pulled the thermostat housing off and..... no thermostat.

Other than the code the symptom was it would get to 25% on the gauge and then take forever to go any higher even when it was 95 outside.

Now it shoots right up to 50% and stays there and the code is gone.

 

think u can sending me everything u order to fix it? I been paying to get everything fix but if it's something I can do then cool.

 

mines go up to 50% and stays there but not sure blwhy im getting the code maybe something is wrong?

I fixed the cylinder misfire. Also I fix my ac but the guy was saying something about cold coming out the hood and hot going in. Im not really sure what that is.
