First mileage check. 22.95 mpg. I'm happy but was hoping for high 20s. Had a bit of idling and I think the timing may be off.

That sensor is in the trans? Did it appear to be unique to the diesel or did it fit other things? I wonder if its got a drac? thing like the trucks that divides and converts the signal for various systems? I also wonder of maybe with no speed input its running in some sort of warm up mode? I know its not fully computerized like the mid 90's trucks but I don't think its as mechanical as we think.

The sensor was listed for other vehicles I don't believe diesel specific either although I did not confirm. I also don't believe that the cold advance is working but I never really checked into it. The dash is not digital when it comes to speed or odometer which would lead me to believe that there's an issue with the cluster. The trip meter is old school and also doesnt work but when you press the reset it moves the tenths number.

Trying er out in this warm weather we been having? One advantage it should have is the electric fans. Not having the fan blowing cold air over the engine should let it heat up a lot faster than those that do have the fan.

This car is going to make me work to get it right. Have a sticky brake pedal keeping the brake engaged you have to pull it up with your foot. Haven't diagnosed it yet its been sitting for a week now. Thinking booster is shot.

Been parked with a brake issue. Road ready again soon hopefully. Retro vinyl mock leather steering wheel cover is installed though.

Does it have a hydroboost or is it using a vacuum pump? I have not had that problem with any car type of setups before, just tractors. Have you been up in the dash to make sure there wasn't a nest up on top of the pedal pivots or something like that?

Update the car has no more sticking brake pedal. I believe that it's been sitting so long the brake fluid is probably bad and was freezing up. I'm going to bleed them this weekend just started driving the car again it's been parked for about 2 months.

Just filled up after putting 168 miles on it since the last fill. Vehicle. 30.43 miles per gallon. Much better than I expected definitely better than during the winter time.

That seems pretty reasonable. I assume its a pretty similar car to my 90 which has the 4.5 V8 and that seems to get around 20 all the time. The 4.5 especially in 90 was a little higher performance than the 4.1 that would have been the gas engine for your 85. Killer for the 90 is it is the first year they went back to high compression since 1970 so it requires premium. Premium has been more expensive than diesel lately.
