Hi guys,

I am getting the P0172 & P0175 codes. 99 chevy k2500 suburban 5.7l
The SES light will come on at different times and go away on its own. This has the fuel regulator mounted under the manifold and I am hoping I don't have to dig into this at this time. Eventually I will probably have to get in here and deal with the fuel spider contraption. Trying to hold off on that for a rainy day.

Any ideas rather than the above listed? Thanks!

 

If it's intermittent, it's probably a wiring problem.

Also, plug in your codes and see what they mean here

Usually only happens when I have to come to a fast stop.

??? Weird deal ???

Thanks CK66. I will look at the link you listed above
