My street driver is a 93 240 2.4 with a 94 940 turbo motor & T5. It has oversized pistons, RSI stage 1 cam & adj. gear with 2 deg. advance, Lostartof chips, 15 lbs. boost on 15g. Ran pretty well first 2000 miles, now it has started to cut out under boost, will actually backfire if the throttle is opened quickly. It started just occasionally doing this, now it's almost undrivable. No ck engine light, drives smoothly down the road. If you keep your foot in it now it will stop accelerating & buck until you lift, worse in higher gears under load.
Any ideas? I was thinking throttle switch, but runs well off boost. I don't have a wideband yet, sure feels like it's leaning out though. If the prepump quit would it act like this? Doesn't matter how much fuel is in the tank. Can cruise at 80 mph but can't pass from any speed.
