My lly wants to surge a little at idle-any thoughts on what it could be
X2 my FPR is bad and surges as well, just to lazy to fix itFuel pressure regulator.. Or FPRV they make a shim kit for them. Not sure if it is fix for it or if it needs to be replaced. I am sure other LLY owners will chime in, as it is a pretty common problem
