surging at wot

TD2593

Grumpy
Ok, Ive got a problem with a friends GN, 86 model. Under WOT or cruzzing with the converter locked the car surges like an ignition problem, The wires are new, new module coil pack, new R43TS plugs all quality parts no cheap stuff. Ive cleaned and tightened all grounds, Tried different MAF. The car is seeing no knock on the turbo link at WOT, fuel psi is good under boost, I believe that the intake gasket is leaking on the under side on the intake, there is a hint of raw gasoline smell in the oil. The car idles poorly after a drive, even after the IAC has been reset and with IAC counts between 20-25, TPS is .44 and 4.80 at WOT ,Please give me your thoughts

Thanks Russell
