Ok, I only have 1 code now it's function 21 bank 1. The leaks and replacing the ccv caused the other codes. I have tried to time the truck several times and wondering if it's a timing problem. Is there anyone in the Sacramento area who can help me correctly time my truck? I have the timing tools and will do most of the work I just need the correct guidance. I can be reached at 661-910-5467.

Thanks in advance
