I have a my97 sti v3 and the engine check light is on the dash, the car seems to fuel cut at 4500rpm. I hooked a boost gauge up to the car last night and it's peaking at 1.6 bar on a standard car surely this isn't right?
The car has no boost controllers or bleed valves, alsomade sure the actuator arm was moving freely and its ok.
I checked the codes on the ecu and it's showing 24 and 33. 24 is idle control solenoid and 33 is vehicle speed sensor.
I replaced the idle control solenoid, replaced the boost control solenoid andalso replaced the maf sensor and the fault is still occuring.
Has anyone ever experianced this before or know what I should be looking for?
