HELP! I have a 2007C3 Pluriel that is hard to start and eventually can run to temp, it will not rev past 2500rpm and all live data is all over the place. I have inj dur times of no1 18.84ms, no2 117.15ms, no3 208.90ms (and static) no4 36.86ms. yes thats what it says on our snap on verdict.O2 sensor says weak, sens1 bank 1 547mv constant, sens 2 2702mv ! and as for battery voltage this reads 0v and when at 0v its hard to start. We found a couple of pins in ECM with slight corrosion and since cleaning it now revs and starts ok but the above readings are all over the place and we have a battery voltage of 0 to 5+ volts fluctuating and dropping in and out.. Before ecm pins being cleaned the car initially would not rev and CAT would glow if held at 2000rpm, disconnected it and no blockage. Fuel pressure a constant 4 bar and smoke test shows no air leaks.We also have no fault codes and no MIL light on and emissions at tail pipe are all ok. Tried to find wires supplying the Ecm but nothing corresponds to autodata diagram. ANY SUGGESTIONS WOULD BE APPRECIATED.
