I've finally got my celiac back on the street after a blown ecu and 10 years.
The car runs fine, the idle is quite stable but i've a little hesitation when accelerating, the rpm drops a bit and the engine quite stalls.
Also the mpg is worst than before something like 20lt/100km !!
I've checked the engine for vacuum leaks, tested for boost leaks, changed the o2 sensor, distributor cap, spark plugs,checked the fuel pressure, i've also cleaned the throttle and adjusted the tps as for bgb.
Nothing!
So i went to the test procedure for the o2 sensor, it could be a bad wiring as i had problems with the distributor's wiring too and had to use an external wire for it.
But the procedure seems really difficult, i've followed it, bridged te2 e1, let it warm up, idling for 3 min, pushed the ac button (with fan speed set to 1) and drove in 5th at 1500 rpm for 2 min... no light come on, so i've disconnected the o2 sensor and tried again, still no light...
I'm running out of idea, how can i check if i'm running in open loop or not? :bangshead: :bangshead: :bangshead:
