I'm getting the 21 or 24 code, but the car runs ok. This is on an E4ME carb. I'm getting both codes but one is becuase my speedo isn't working.
I don't really want to replace the the TPS, I'm just wondering what kind of damage or problems this sensor malfunctioning is going to cause me.

Mine was reading 5volts all the time when it went bad, had an off-idle bogging problem, and the torque converter locked up too soon. Bad gas mileage also. Not sure if it'll damage anything because I took care of it in short order, but sometimes if your mixture is too rich you'll smell fuel in the crankcase, which is never good for the internals.

when i first bought my car i also got those codes. the issue i had is that the car was extremely slow to respond, very little power in the low rpm range, and no 0 to anything power. it was this way for almost five months and i never saw any change in the performance for better or worse, after changing the tps i immediately received what seemed like an insane amount of power. the car had horrible gas milage as well during the bad tps months. i would reccomend changing it if possible i think i picked one up at auto zone for fifty bucks.

The TPS is not that hard to check. I don't have the actual specs, but I can get them. With a volt meter you just look for a smooth resistance change as the TPS turns. If you find any dead spots or sudden spikes, its bad. I can get you more info if you want it. If its bad you will get syptoms like dvardaman85 described or you might find a bad spot at a particular speed. Car runs rough only at a particular point in acceleration.
