Vauxhall Omega 2.0 16V (116K mls)
ECU light stays on after starting. (Has done for about 6 months!) but goes out & car drives ok after rapid ignition Off-On.
In addition Recently: Engine dies when warm (Rev counter also dies completely although engine is still turning when car is still in gear). Again returns to normal running if ignition turned Off-On quickly.
Checked Fuel Pump/Inj Relays & both are ok. Changed spark-plugs. Cam sensor does not seem to affect warning light. Haven't been able to check much else.
Any Ideas & suggestions would be appreciated as car is a good runner. M25 daily is a bit dodgy at times though, when the thing plays up.
I have already seen the advice regarding ECU's & will see if the Fault Code trick works.
In the mean time HELP!!!!! Pleeeese!!!
