my new '74tii has an APPETITE for fuel

[Guest Anonymous]

I have jsut got a 1974 2002tii, It seems to run fine and drives really well, my dad drove it for 1600klms and said the economy was good, then when I drive it (city driving) it used 30litres in a week when my old 1984 323i guzzler would have used 15-20ltres with the same amount of driving, and No I didn't totally thrash it

Any help would be great,

Thanks guys,

test the cold start injector: remove the two socket head cap screws, aim it into a glass jar, plug the hole in the intake manifold and have someone start the car. It may be hard to start without the extra injector, but you should see a temperature-dependent fine mist of fuel for a second or two on start-up, then the fuel mist should stop with no dripping.

Dripping means leaking, and there's your poor fuel economy.

Otherwise, the linkage is suspect, any you'll have to get it right. New pieces are available, as is the gage to set them; also the synchronization between the pump and throttle valve. There's a lot to mess with on a tii, be sure you are capable, and will acknowlege responsibility for your tinkering, or take it to a pro.
