Over fueling on 350i

[PaulMarshall]

Hi new owner in need of help.

I have a overfueling issue. The injectors are being energised for 20 ms instead of 1ms max 12ms. I have replaced the throttle potentiometer with no success. My local garage has had the car for two weeks and can't identify the problem.

Anyone any ideas or come across this problem before.

Thanks

Paul

Hi Mark

Are you saying the ECU fitted is a Range Rover ECU?

Thanks to everyone else for their help and advice

Has anyone got any idea if the ECU was common with other cars. I would like to try one out before buying a new one or getting the old one repaired

Thanks guys.

The garage agrees with the diagnosis on the ECU and has sent it to Lucas for testing. Hopefully this will be the proble. I will let you know what the outcome is.

Hi Guys

Got the feedback from the garage todaqy. The ECU was sent back to Lucas who sent it out to their repair company. Feedback from them was 'It tested ok but the symptoms are known with this type of ECU'
The garage's problem and mine is if they can't find the problem with their test equiptment now, how can they be sure of repairing it.

Help any idea's guys

Hi Guys

Finally got the car back on Friday. It dosen't over fuel any more but does occassionally cut out. It starts again with no problem. The garage changed the fuel filter and disconnected the cold start injector.

Hi Euphoria

Over fueling is when the injectors are energised for too long pumping excessive fuel into the engine. Usually this will flood the engine and petrol will find its way into the exhaust.

I should say that that is my definition. Any takers on a better explaination(preferably more techincal)
