Omega General Help / Re: engine not responding while rpm`s falling to idle

« on: 21 December 2011, 10:59:17 »

is it possible that the electric fuel pump in the fuel tank isnt working properly, but the car accelarates great. I dont know.

is it complicated to replace the fuel quantity regulator by my self?

regards

Omega General Help / engine not responding while rpm`s falling to idle

« on: 20 December 2011, 11:18:52 »

Hello to everybody!


I recently bought a 99 opel omega 2,5td (x25dt) that in general runs smoothly but with a little annoying fault. When driving and for instance shifting from 1st to 2nd gear at 2000-2500rpm the engine cuts fuel to to the injectors for about 3 sec at the same time the throttle pedal is not responding and the ECU light comes on, for 3 sec or till rpm`s fall down to idle (600-700rpm). The only trouble code that comes on is 64 ( fuel quantity adjustment control). On the other hand when i drive more robustly ( from 3000rpm+) i dont have any problems at all. just that gap between idle and 2500 rpm.

I have checked for leaks, there were none, I have tried a STP fuel line and nozzle cleanner, it maybe helped a little bit but only with engine performance.

the mechanic says thath the injection pump should be replaced/serviced, what do you suggest?

with many thanks! i wish you pleasant holidays
