16 Valve, Terrible gas mileage!!! 700

Hello.
I have a 1990 745 with the B234F engine. Latley I have been noticing that I am getting absolutley pathetic fuel mileage. I know I have to replace the harmonic balancer, timing belt, balance belt, and T-belt (and covers). Just wondering if anyone thinks that any of that would cause my bad mileage. I've been mostly seeing it on the highway (65-70 MPH) to go from Cape Cod up to Boston, about 50 or 60 miles total.. I have changed the plugs and air filter, still no change.
