I HAVE A 94 WRX IMPORT WHICH WAS HITTING FUEL CUT UNDER BOOST I CHANGED BOOST SOLENIOD AND SURROUNDING MODULES BUT THE PROBLEM STILL PERSISTS THE MAF VOLTAGES AND RESISTANCE'S ARE FINE AND NORMAL ANY IDEAS!!!!!

 

change all the vacumn pipes first for silicon ones or similar , had same problem with my94 boost . also if you have a boost gauge pull the pipe of the back and blank it of as sometimes the gauges leak boost without you knowing !

 

check the restrictor is present in the vent pipe from the 3port boost solenoid..

what mods has the car got?

Simon

 

MODS ARE ONLY A INDUCTIONS FILTER AND THE RESTRICTOR OR ORIFFICE IS PRESENT AS THAT WAS REPLACED AT THE SAME TIME WILL TRY OUT SILICONE HOSES AND BLANK OF BOOST GUAGE CHEERS CHAPS!!

 

standard exhaust?
