1991 GTFour RC, it's having an intermittent problem where it will trigger fuel cut and throw a CEL for code 34 when the car isn't actually making much boost (if any). It's happened a couple of times when doing longer climbs up hills at 3-4psi and also once while turning at a traffic light. All just moderate throttle situations. After it happens the car seems to be ultra sensitive until I restart it. My boost controller has a very conservative boost cut function so I unplugged the factory MAP sensor on the firewall and the factory boost gauge is now pegged at max. I figured this would take care of the problem for now but it just happened again and now I'm at a loss. I was figuring the sensor was defective but now I'm thinking maybe the ECU is being flakey? How else can it be throwing a code for overboost without a pressure sensor?
