Currently trying to figure out the code reasoning for P1101. I have replaced the MAF sensor and put in a new air filter, replaced the coil pack, an O2 sensor and the gasket on my motor, put new transmission fluid in it and an oil change.. The problem started as it would start sputtering when trying to get on the highway, check engine light would come on for a day then shut off. After we replaced the MAF sensor and air filter we test drove it on a back road climbing a hill. Once we started to lose power and tried to give it more the check engine light would blink and a message would pop up saying Service StabiliTrak and Service Traction Control. Before we replaced those it would do the same thing but over heat, but now it's doing it again. I have looked up everything I could possibly find and read other forums on here of people having the same problem but found nothing helpful. Any suggestions as what it could possibly be or maybe to check that we might have missed?
