Check the throttle valve for dirt; check the throttle linkage. Use carb cleaner solvent spray.

is it possible that a bad fuel injector can cause this weird idle?

If there's a bad fuel injector, it'll most like cause the idle speed to decrease and be rough.

also check vacuum lines for leaks and or unhookedness(yes i made that up) generally a vacuum leak will cause an engine to idle higher because its getting more fuel dumped in than air causing a rich condition

car cost=$500 total parts cost so far=$4750+
