Question about 2006 Scion tC
I have 1994 mercedes c 280.
the idle is low and then hi and gas smell is coming form the car, exhaust- it smell strong. and am getting horrible gas mileage.
This should show up easily on the ECU diagnostics computer at a mercedes dealership. Basically your fuel mixture is way too rich causing your car to be heavy on gas, have a raw gasoline smell, and not run right. Something like this can be caused by a defective oxygen sensor (but that usually produces a check engine light) or it might even be a defective ECU. There is really not way of knowing for sure until you do a proper diagnostics where they hook up your exhaust at the same time and do an emmission test. In most cases it's some sensor that needs replacing.
