This car has an upper pulley, JLT intake, Ford Twin Blade Throttle Body, runs great, fuel trims are good, WOT fueling is good, power, drivabilty good.
I have one issue that I can't seem to shake, the throttle will hang open at WOT when rpms are 5000 and Higher and you push the clutch in.
every where else the car drives perfect.
Any ideas?
