Re: Fpr Ques

Unplugging the FPR will not give you more fuel pressure at WOT. At WOT there is NO VACUUM going through the line . The FPR lowers the fuel pressure at idle and as the motor vacuum drops, the fuel pressure rises. Your manifold vacuum is 0 at WOT. Your car will run very rich at idle and foul the plugs with no vacuum line.

any mods to the car to warrant your lean condition?
