Hi ,

I try to explain 2 situations where Omega (2,2 bensin, mileage 245 000km, manual) starts behave strange. Might be that these are related to the same sensor or problem:

• When driving during a lot of rain (90km/h) the car engine engines starts to create small vibration when adding more gas. Strange noise comes in during acceleration. I do not know, if the lambda or crankshaft sensor becomes wet in those conditions and gives false data to the ECU? This behavior is noted always when driving very wet conditions. And no DTC-s detected after the events.
• Another story is during cold morning -5C/-10C, the engine starts well with the first turn. 5-8 seconds runs well and then shuts down. After second ignition turn the problem disappears. And I have noted this also just in cold mornings.

If anybody has any similar experience, I would be glad to start discussions. I have a feeling that is electrical related but.....
I have OBD and garage to able double check the recommendations.

Cheers,
Olari

Check plugs wells, esp No4 for water - often rain comes through scuttle into No4

The plug wells and coil pack was cleaned 2 weeks ago.

I recently changed:
- new fuel filter.
- cleaned the butterfly valve.
- new plugs

That is just additional info.
