I have a 1994 GMC K1500 5.7L, the previous owners switched from the standard exhaust system to headers. How do you properly change from a standard exhaust system to a header system??
We are having issues with power loss and cannot find what is causing it. We are finding
many different things that were disconnected and removed that probably should have
Good luck. It's not easy to give you a good answer here. Check the vacuum lines that are not disconnected. Start there.
Well. You need of sensors. If they aren't there then that's one problem
We have checked a lot of sensors on the truck MAP, EGR, Throttle position..etc. Is there a way to find a complete list of sensors that should be on the truck?? We changed out the plugs, wires, button, and cap today and checked the fuel pressure, everything looked good
As far as we know all vacuum lines have been checked and are good
you need to make sure you have the o2 sensors still
