[QUOTE="ForcFed93, post: 15621202, member: 24561"] So, given what ZeroDCX has said about the fuel trims, it would appear to me that STFT's in the 30's under hard accel and mostly positive values even at idle and part throttle cruise (the negative values were mostly under coasting/decel conditions) means the car is trying to add fuel to correct a lean condition. The higher the values, the more fuel it's trying to give (and probably can't give enough). I'm guessing it's a fuel pump that's going bad. Not to mention it appears to be getting progressively worse. I pulled the vacuum line at the FPR with not a trace of fuel smell at all. Anyone else have any thoughts? [/QUOTE]
