20 Most Recent 1990 Lincoln Town Car Questions & Answers

browntoni22: the code it self is "Potential short in Air Bag system"
You are playing with Explosives!!!
Working on a safety restraint system can be very dangerous if you don't know what you are doing. There is a procedure to diagnose the problem which entails using a jumper wire for part of the diagnosis. Just as an example: emissionwiz mentioned a clock spring. This can be damaged by the installer very easily if they don't know what they are doing.
It is designed to rotate only so many revolutions. IF the installer was not paying attention and the clock spring had been out of the packing prior to their receiving it, it could have been rotated one or several revolutions. So when the installer puts the clock spring in place and goes to turn the steering wheel in one direction, it's fine but in the other direction, it will destroy the part!
Anyway, to sum it up in a nutshell, leave this job to a pro.

Hi Joe, what you need to do is go to a trans. shop and have them adjust the TV (Throttle Valve) cable. You can do this yourself but you need a really low PSI guage. When the line pressure is at 0 - 5 PSI, it will be adjusted properly. Usually only trans. shops will have the proper tools to do this. It's very important that the TV cable is adjusted right on the money or you'll smoke your transmission.

Try turning over the engine with a wrench, manually. It might be seizing up.

First try to turn the engine over manually. If that's ok then try this:
While you're trying to start the car, have someone bang on the starter, under the car, not too hard. This will usually un-jam the pinion gear and it will turn over.
I had to do that and it worked great. Then i Just washed the tip of the pinion gear in a cleaner and it's worked now for 15 years.

Hope this is not it.

No, not likely, freeze plugs are down on the sides of the engine, big, 1 1/4 dia plugs. If you have a leak up top under the thermostat, it is possibly just the gasket, easy fix, check the thermostat while you are in there, get a big pan to catch the coolant, reuse it. If it is not there, a lot of new cars have pipes running back and forth under the intake, They spring leaks all the time and nobody knows what is leaking, especially when it drips down the back of the engine and everybody thinks it's the tranny.
