Going to get the code now. The truck doesn't vibrate when I switch it to 4 wheel drive high range. So, I can't tell if it is front end, rear brakes or the injectors. Code is solid.
07 Silverado Classic Cat-Eye Z71
I have vibrations at highway speed, but only when it is hot outside. Hit the brakes and vibration is way worse. Check engine light is on with bad injector code. Just need to figure out what is going on. Thanks for any assistance.
