2009 GMC Yukon XL 5.3L 2WD
Stabilitrak off, reduced engine power, P2135 Code went off again today. My wife was driving about 65 mph. Hadn't been in the car maybe 3 miles, when it went off.
I've read the TSB. I've replaced Throttle Body, TPS sensor, Pedal and sensor, MAF sensor, TPS harness, all AFM lifters, DiabloSport delete of AFM.
Don't know what else to try. Wife loves car but is seriously considering trading which cost $$$$$. I hate not being able to solve this problem and sure don't want my wife stranded.
Any help out there?
