Question about 1996 GMC Yukon
I have a 1996 5.7 Vortex Yukon that idles good, accelerating from a light great also but when I am driving at a steady speed it jerks and check engine lights up flashes then goes away. I already changed spark plugs,wires, and coil still same problem can anyone help.
I think it is the injector assembly i replaced with the new system that has cannon plugs or the wiring to the injector>> so i am going to clean and put some contact cleaner on it and get back with you

I have a 1996 gmc yukon 5.7. When driving down the road at a steady speed it will start to **** but if u give it more gas it goes away then comes back once u level out at a speed. It also jerks bad when u give it gas goin down a hill. What i've noticed is it seem's to come at certain rpms between 2000 n 3000 which is where it all ways rides. I've had every sensor changed along with a new jasper motor. It still jerks so i took it back to the garage and we tried changing the tork converter because it seemed like it would'nt lock out but it still does it. It is very nerve racking so if any one has a suggestion please let me know...
