2007 Avalanche LS 5.3L
Husband drove approximately 10 miles when the traction control light came on, oil light came on and constant dinging. Checked the oil and it wasn’t showing anything on the stick. Replaced the oil pressure sensor and did a complete oil change, didn’t fix the problem. Put a code reader on it and got 2 codes P0641 and P0107. Replaced the MAP sensor and seemed to run and drive fine, until this morning. It was sluggish going up hills like we weren’t getting enough gas, couldn’t go above 50 and didn’t want to seem to go into 3rd gear. As we pulled into the gas station, all the warning lights and constant dinging came back. Turned it off and when we started it back up, it was fine but still sluggish, until we got to work and the lights came back on. What could be the problem?

Thanks in advance!

 

Is there oil in it?
