My Uncle gave me his truck to fix. The truck idles rough. But smothes out on excelleration. He replaced the cats for they where glowing. All the cylinders have almost 170psi I have replaced fuel injectors. Still the problem exist is there a way to check timing on a truck with a coil pack if so how?

The fuel pressure is at 40psi I got the right timming from the dealership but the problem still exists. Do you think the injectors are running wide open?

They can infact be hanging up and not shutting off or just being told to be on tooo long.

Do you have access to a noid light?
