Anyone any ideas?
After getting my Timing Belt, RCM Oil pump and oil/filter change done at AWD, the car was fine all the way down the road. Left it for 5 days when in London. Took it out tonight and within 1 mile the CHECK ENGINE light comes on, but the gauges all read OK, AFR looks fine to rich.
Tried it out when I was coming home tonight - it hesitates under boost then seems to boost harder and the light goes off but when I drive normally again after 30 secs the light comes back on. It goes out when I start the car, but pretty much stays on all the time.
Boosting @ the 1.1 bar it is set at but then will dip etc. Anyone got any ideas?
Is it a sensor, timing, airlock, a hose etc? Too dark to check it just now.
Oh its' a 1994 STI, no cats []
