If the mixture is SLIGHTLY out of adjustment it would have a major effect on the gas mileage and not affect the idle quality. The only way to properly adjust the fuel mixture unit is to hook the engine up to an exhaust gas analyzer. The bad sound you hear I am taking a wild guess is the bearings in the idler pulleys by the air conditioning compresser. To test this guess take off the belt and run the motor for a minute. If the sound goes away change the bearings, it's not difficult. Condition is not predicated on mileage although it does have an effect, low mileage cars sometimes need more work to get them roadworthy than a well maintained higher mileage car. I have seen VERY low mileage cars without recalls, origional fan relay, rotten battery, sludge for brake fluid, slime for anti-freeze, shoe polish for gasoline, you get the picture. The car was purchesed new driven alittle and then "stored" until it is worth a fortune. While it may not have any interior wear and the outside has no dings it will take a lot of "love" and tender care and EXPENSIVE PARTS to get it reliable. A car such as described is a good candidate for concours without alot of work but to be a reliable driver is a long way away. Sadly people with a car to sell such as this want top dollar when in reality depending on how much you can do yourself you could spend $5000. on it. I know it's hard to believe but if you don't prepare for it and budget the money and do all of the work the car will disappoint you regularly when it doesn't get you home. No matter how good it looks on the outside it is still 20 years old.( sometimes so is the gas, brake fluid, anti-freeze, heck you get the picture again). David Teitelbaum vin 10757 it didn't have 20 year old gas but everything else probably was! including the windshield washer fluid, did it stink! --- In dmcnews@xxxx, Joe Palatinus <jpalatinus@xxxx> wrote: > I have been trying to solve my 15 miles to the gallon problem for quite > some time.
