GMC envoy xl
So for 3 months I finally figured out that my rough
idle problem was caused by my o2sensors and I
also did fuel injection clean.my pcm doesn't need
to be updated as well that's why I had no check
engine light there are a lot of people with this issue
and I put in a recall as well
You put in a recall?
Yes wrote and called and if enough people have complained about this then the dealer will fix everyone's at not cost
I did this the other year with the wiring issue in the door they allowed me to have it fixed at no cost so everyone should have gotten a notice from the dealer about it idk if anyone did but I got a letter stating that my complaint was approved and several had this issue
