A little help please!!!
I'm getting a couple of codes on the Vette. They are: P 1120
P 1220
P 1516.
What do you think I should do. I Pulled off the Vaccum lines at the throttle body and the one that's on the pass. front of the intake. I capped them off. I cleaned the air intake boot, and wipped out the inside of the throttlw body. And now, my car is in "Reduces Engine Power" and I have these codes... Please help. I just want my car to run...
Thanks
