I have a 97 SC2 with the same problem, I've only lost 60 mile per tankful at this point. Chamging the Plugs and wires are a good thing to do, at least check your plugs. Mine were in very poor shape and I had alot of arcing between the boots down at the coil packs.

The down side is that, replacing all that stuff did not improve my mileage one bit.

My next items to attack are the O2 sensor (in the exhaust manifold), and the coolant temp sensor.

I had a good O2 sensor laying around and I replaced that, but that did no good either. So today I plan to replace the coolant temp sensor and try that.

I will let you know what that does.
