So I have been hearing some weird noise in the motor (like a loud lifter) under WOT and couldn't pinpoint the sound. well I just added an A/F gauge (had it laying around, put it to use) and found out that I'm leaning out under WOT (yes eventhough it's a narrowband) and thus concluded that the sound is detinition.
Well tonight I just did a fuel pressure reading and at idle with vacuum connected i'm at 30 psi and with the vacuum disconnected i'm at 40 9both right at the bare minimum for spec with Haynes) . but there was no significant difference with how the motor responded when i disconnected the vacuum line to the FPR.
Should I suspect a faulty FPR as being the cause why I'm leaning out at WOT?
