"Fun to drive / own, but too many mechanical failures"

What things have gone wrong with the car?

I've had the usual repairs listed on this site as well as other Intrigue web sites. Crank position sensor, front turn signal sockets, intermediate steering shaft, oil consumption, etc.

My question is this. I hear of others getting good gas mileage, but I do not. On a highway trip I believe I only got about 24 MPG. In town it's considerably less. That's not consistent with how it was originally rated nor with what I hear from other owners.

Will changing the oxygen sensors do any good? Thanks to all who reply.

General comments?

I love the styling, handling and overall performance of the car.

With the costly expense of replacing all the oxygen sensors, the best bet would be to get a couple cans of sea foam from your local parts store. You simply find a vacuum line to the intake manifold that sucks air while the car is running. Once you find one, crack open a can of the sea foam, insert vacuum line, and idle between 2,000 and 3500 rpm. The car will smoke and stink badly for about 30 to 45 minutes. Once the majority of the smoke dissipates, it's safe to drive. Check out a 25 mile trip on the interstate, it should be fine.
