93 Tempo ideling at high RPM's
93 Ford Tempo -- 1.8 FI 4-DR
When I start the car, it is ideling too high.
I've checked the throttle cable and springs and they aren't seized up or anything. Is there anything computer wise that may be causing this?

I agree with BeJay.
Using autolibrary.org in my signature file below, check the IAC valve for fault and clean the throttle body with the proper Ford approved cleaner (from the dealer).
P.S. Your Tempo either has a 3.0 or a 2.3, not a 1.8.

If you don't have access to a multi-meter, you can always pull off the old IAC, clean it with some carb cleaner, re-install, and see if it makes any difference.. This isn't an intended repair, but a very quick, cheap way of helping define the problem...Of course if the IAC is actually shorted internally, then cleaning won't make a difference.. But usually it's more a case of being sludged up..

If you're careful, you can get the gasket off without doing damage to it..Again this isn't a repair method, just a cheap way of checking it out..But if nothing changes, most parts places sell just the gasket.

if it is a plastic iac you probably shouldnt clean it as it will be more damaged than it is right now as carb cleaner tends to damage the plastic diaghram inside. however if you are just trying to determine if its the problem start the car up and disconnect the iac connector this should cause the car to idle very low or die if the iac is working correctly, if no change remove the iac and place your fingers over the holes one will have vacum on it now have someone start it and it should either idle very low or start and die, still no change means you have a vacum leak somewhere and should look elsewhere.
