Hi. Yesterday I installed a high idle kit to my 2003 duramax lb7.
I tested it and it worked fine. I was driving home it felt sluggish and lots of vibrations.(I turned high idle off) When I got home after driving for about an hour my check engine light came on and it was fuel pressure rail?
I cleared the code and took it for a drive and than my truck started to sound bad like a hard knock and almost stalling out. I had to keep giving it fuel.
My truck always had a tiny surge once in the while. I googled it and said my fuel pressure regulator could be gone. But I'm thinking I ****ed something up to the ECM when I was installing the high idle. Is that possible? Please help me ASAP I need to fix this issue.
Thanks !!!
Also I have a bully dog prog and bone stock duramax
