rough scratching noise at start up
Ok so when I go to first start my truck in the morning or after its been sitting for a while. Right after the engine turns over this loud high pitched screeching noise comes from the engine bay I believe I havent been able to pin point exactly where but i think the engine bay.
I thought it was the fan scratching against something but its not its always right after the engine turns over or while its ending. I really need help I have no ideas what this would be. I was thinking lifters, the cam synchro problem that plagues the 3.0 I checked Tranny level and oil all fluid looks good.
Im also throwing a CEL as well I just kept on resetting the engine its the dreaded P0174 lean in bank 2 have not done anything for this but it did come on after I got my exhaust done after the last CAT.
The code has been on for a while and I believe that this noise started after the code has been up for a while.
