Question about 1994 BMW 3 Series
Posted by Anonymous on
I am assuming your old air flow pipe was ripped ? If that was the case it can often damage the air mass sensor / meter, they are quite delicate on these cars. the other alternative would be the throttle control module although these raely go, do all the air pipes have a good tight seal around them? any air leaks will cause the car to be sluggish.
Hope this helps, as regard to the clocks not showing mileage is the back light lit up?

You have a couple of issues - hesitation at speed most likely cause is fuel filter. And since you mentioned you changed airflow pipe & plugs make sure air flow tube is tight and no kinks or cracks and all little vac lines are tight.
Speedo/clock not showing miles is a dash motherboard. The E36 was notorious for this and other quirks. Stop by BMW dealer and have tech show you how to do dash self test. There's a simple procedure (it just slips my mind currently) by pressing a couple of buttons and turning key and the dash actually checks its own functions and then displays info in your driver announce area (display in speedo "door ajar, taillight", etc)
