To adjust the idle on a 1989 Ford Tempo, first, ensure the engine is at operating temperature. Locate the idle air control (IAC) valve or the throttle stop screw on the throttle body. If you're adjusting the throttle stop screw, turn it clockwise to increase idle speed and counterclockwise to decrease it. After adjustments, recheck the idle speed using a tachometer to ensure it meets the manufacturer's specifications.
my 89 ford tempo goes 85
Follow top rad. hose.
Look under the dash between the steering wheel and the door.
Throttle plate may be stuck - try to free with a screwdriver
There is very little chance this will work.I believe the Tempo is much closer in design to the Escort series than the larger Taurus/Sable.Personally, I wouldn't pursue this particular effort. Find one from a Tempo/Topaz.
If your engine is ideling fast its probably temperature senser. There is no adjustment for idle. that last answer is not entirely true. u can adjust the idle. but it depends on if its a throttle body unit that looks like a carburetor or a smaller unit. on a TBI unit, there is a screw u can adjust but the only way to adjust it is with the right tool. its not a Philips screw or straight blade. but if its idling high or fast it might be the idle air control valve. the one went out on my 1985 sunbird and caused it to idle funny.
89 tempo engine will work
Well, if it is a 4 cyl, you can see it right at the front of the car. Look down between the engine and the rad.
If they have not changed from the '89, then take off the glove box door. Its there. Just remove all the small screws then pull it out.
The fuel pressure for an 89 Ford F250 with a 5.8L MFI is between 13 and 20 psi with the engine at idle. With the key on engine off, the gauge should read between 23 and 31 psi.
there is self adjusting mechinsms in the drums. Just keep them lubed(ani-seize)
If the idle is constantly high, I would adjust the idle control on the left hand side (facing the car) of the throttle control body.
