Shakey, hesitation, and sputtering at gentle throttle
Any idea what would cause sputtering at 1500 rpm? It happens cold or warm. I've only really noticed it when trying to slowly bring up the rpm in neutral, and it isn't really much of a bother when I'm driving, because if I give it even moderate throttle it will go right past that point without any problem. I was wondering if it might be a dead spot on the tps or what?

lol i would think if its bucking it would be b/c the flywheel has hotspots on it basically the little hot spots cause bucking on a 5spd...put some lucas in there and drive at that rpm or an extended period of time it will work its self out... fairly sure that would be it

Oh, and btw, I'm fairly new to automotive maintenance beyond oil change, coolant flush, plug wires, you know, simple stuff (Prior to my 7 I drove strictly hondas and toyotas, so little or no maintaining required) so exactly what do you mean when you say "put some lucas in there"?

my car did some weird hesitating at SLIGHT throttle, but fine after that. it was the TPS. set the TPS and see how that works. if it is not fixed, check the TPS with a voltmeter. if u dont know how to do either of this, search, or ask in this post

I appreciate all of the suggestions, and I'd like to hear more if you've got them. I really want to find out as much as I can about possible problems before I start shelling out cash to fix this issue.

oh here we go with the lucas enthusiasts..... it fixes any and everything! hah i use it with my cereal it's so good. IMO if you need lucas to fix your car, then there's probably a problem that you need to be dealing with other than prolonging it.
Anyways i would be betting on the tps but surely you should "exhaust" your other free options haha. I know for earlier models there's a ground wire mod you can do to prevent the hesitation although i don't think it applies for your 89 gtu. I'm sorry i couldn't be of much help, goodluck with finding the problem!

I would just buy a new one and try it, but they are like $300 new and $75 or so on e-bay, and personally I've never trusted used electrical components.

dont listen to this guy. if you know they are correct dont switch them. it could cause permanent damage.
if you dont have a volt meter then just screw the TPS inward little by little (test every adjustment). you should be able to fix it by doing that. make sure your throttle plates are opening correctly and there is no air leak on the intake.
