03 suburban issues
Hello everyone I am new to this forum so of course I'm having problems with a vehicle. It is a friendship 03 suburban w/ 5.3L. The issue is that sometimes the vehicle will hesitate when accelerating and then won't go over 20 to 30 mph. And for some reason it doesn't throw a OD ll code but it shows on the digital part of instrument cluster. I have cleaned MAF sensor and replaced throttle body position sensor. Any other ideas?
