the 1993 Ford Aerostar 4.0L AWD has started shaking and vibrating very bad. Is there anyway to disengage the AWD without taking out the front driveshaft and transfer case??

I have a problem with my idle speed, when you first start it, i will idle to 1300rpm, then quickly drop to 1100rpm within just a few seconds, not long after it will drop to 1000rpm....

Here is where the issue comes in.... it takes about 15-20 minutes for the rpm to drop to 850ish. once is there is still doesnt seem to want to drop back to 850, it will stop at 1000rpm before droping back to 850ish.

Not sure whats causing the problem. I recently rebuilt the engine, which means it has a brand new intake gasket, and TPS, filter, and hoses.

Let me say that the idle is smooth and there is no misfire. So since its smooth and there isnt any misfiring, im tempted to say its a sensor but not sure, the only sensor i can think would be the oxygen sensor not reading right.

Thanks for any input

I add antifreeze at least once a month and now its overheating.

I also hear a knocking or popping sound during acceleration.
Two diff. problems.

tranny won't come out of 1 gear can it be anything else i'm missing or do i need to replace the whole transmission

I never had problem until new rear differicial installed 3 months ago. When street is wet it is bad if I go over a bump or a railroad pass in the road. The rear will seem to slid to right then left.

could the restraining spring cause this to happen? I notice its missing on the side I hear the grinding.

they only occur after the firlst time i start it in the day then after that it seems like it has trouble turning on then when i drive sometimes it accelerates by it self or trys to turn off

I just got my saab out of shop, now it is overheating there is no leak in the container that holds water or antifreeze. Help

theft system wil not let the car start

Its a long bed automatic and has a tilt wheel if that makes any. Difference

codes cam sensor ! how do I make sure thats what it is ?

Hello, When I turn on my headlights my rear right brake lights does not light up when running. It only lights up when the brakes are applied. The reverse light does not work at all. I have changed out the light bulbs and have checked the fuses. Also my top light is out. How can I fix this problem?
