To recap, a few months back I drove from Vancouver to Calgary. (For those in the US think about driving from Seattle to Montana). Most of the way my car was fine except when I got up into the Rockies. I seem to lose all power and even with the pedal floored it would not go past 5000rpm. I figured this had to do with the air pressure and thought my sensor must be shot.

When I got back to Vancouver I started to notice that I was getting really bad gas mileage. I would average around 200 kilometers (125 miles) per tank of gas, where as before I would get closer to 400 kilometers (250 miles). I also notice that sometimes my car would not start on the first turn of the key, I would have to turn it twice for the engine to catch.

I took it to BMW and they said all the sensors were working fine but I had an intake gasket leak. So I had them fix that but still had the same problems. I took it to an independent BMW specialist and he suggested that my 02 sensors might be dead. So I had him replace that and I did notice that on the highway I can get over 400 kilometers (averaging 9L/100K) per tank. However once into the city the fuel consumption skyrockets to 25L-28L/100K and I am back down to getting 200 kilometers per tank. I am still having the starting problem as well.

So does anyone have any suggestions? I realize these cars do not get great gas mileage but why the huge difference between city and highway. I thought that in the city I should be getting closer to 15L-17L/100K. And on the highway keeping it steady at 100KPH (60MPH) I barely get 400 kilometers per tank. When I first bought the car I could get 400 kilometers in the city!

I should mention that I have the TMS chip, Euro air box and a free flow exhaust. I put all these mods on after I thought I had this problem fixed. Now I realize I should have waited to make sure but I donít think these mods should be affecting gas mileage that badly.

This has been an ongoing problem and I am getting extremely frustrated that no one can seem to solve this. I have taken it to the dealer and 2 other independents and every time the actual problem does not get fixed. I hate to say it but I am almost tempted to sell the car and buy an E36 M3. Boring car but infinitely more reliable than my E30 M3

Anthony,
By the way, if it so happen that your
problem is cause by a clog catalytic
converter, dont wait to long to fix it.
this situation is real fire haszard.
