[QUOTE="aaron97, post: 6290775, member: 66010"] Changed them last week.. Good to know... Well, with the FPR disconnected, he drove around for 30 minutes and didnt get a CEL. Here are the PENDING codes (P0411, P0402, P0171) and thats in the order that they appeared. The CEL is still not on, AND with the fuel pressure higher the long and short term fuel trims are down around 0-5 percent on both sides. So I think now we are going to get an Adjustable FPR and raise the pressures to the maximum limits and see how that does. On another note. I dont think i mentioned it before, but one of the IMRC cables broke and he drove around like that for a couple days and never got any codes related to it. Only found the cable because he pulled the intake off to get the injectors out and noticed the cable then. It actually broke twice. THe original cable broke and then the home-made cable broke. Its all good now, but i was wondering why with one cable broken didnt it throw a code? [/QUOTE]
