I normally fill up with about 44 litres when the fuel light comes on after doing 430 to 450km city driving (approx. 10km/litre).

My 1991 190e 1.8 Euro RHD has a 55 litre fuel tank as per my Haynes manual.

I have yet to reconnect my MM to my EHA harness and take the readings again while driving.

A recap on my car's existing setup - EHA off and fuel mixture leaned to the point that it idles a little rough.

Problem - car running too rich with EHA on/off, black smoke and severe hesitation off the line.Suspect "more than necessary" fuel being dumped while engine is running.No external fuel leaks and gas mileage horrible - 260km when fuel light goes on.

Meanwhile, my latest findings since spraying the underside of the FD (by pushing down the airflow plate) is that now when I park and leave the car idling, it doesn't leave a sooty mark on the pavement.Before, 2 minutes was all it took to get a sooty spot the size of my palm on the pavement.

Before the carb cleaner trick, even with the EHA off and mixture leaned, the car would still hesitate slightly off the line and smoke if accelerated hard.Fuel mileage closer to 300km when light goes on.

My tank was only left with 1/4 when I did the carb cleaner thing so I'll top it up today and clock the fuel mileage.

If it improves, my next step is to richen the mixture with the EHA on and try to get the car in closed loop.

By the way, I have been following your threads for a while and all I can say is GOOD JOB!

I will report my findings and further checks/tests as I go along.

Thanks guys.

Cheers.
