Morning fellow GM owners,

So i figured out my ABS light, bad sensor on the front right hub, Prob do the whole hub. Anybody have good or bad experience with the NAPA hubs for our trucks?

On to topic at hand. I have been chasing a #7 missfire. I have put new plugs in, swapped ignition wires and even swapped #5 and #7 coil. I will be doing the knock sensor replacement soon. so if its a intake issure hopefully a fresh intake will seal her back up. Is there a way to test an injector? Even if i take it to the stealership to have them hook a tech 2/3 to it and test it that way? Its been a good truck just trying to get the check engine light off has become a chore and a half! still have to figure out the buttons for the DIC system.. which dont work.. but oh well.

Thanks ahead of time

Possibly try swapping the injectors? That would be a little bit of work but could be valuable information to yourself.

Could be a burnt valve or in the case of the propane fuel injected model that I propane company around my area had...... The valve and valve seat completely disappeared (I DONT KNOW WHERE IT WENT, motor came in everything was tight they didn't not even bother with draining the oil from the engine).. Hopefully that is not the problem. But a bad valve that is not closing all the way can cause the computer to think it is missing.
