SOURCE: removing gas tank on 1991 geo storm to replace fuel pump
I would suggest you get a Haynes repair manual for your Geo. They are GREAT manuals and cover just about everything from small repairs to even doing a full engine rebuild. I use them all the time .. full detailed explanations and pictures/diagrams. The whole process from beginning to end to remove your fuel tank is even in the manual.
Here is the link to the manual
SOURCE: Severe lack of power 1991 Geo Storm,
When you say "fixed", do you mean that you put the new belt on it?
If so, you probably missed a tooth in the belt placement. This usually happens when you wrap the wrong way during the procedure and the marks don't end up lining up.
Also check for other things like pinched wires or something disconnected that didn't get put back in the right spot. (vacuum lines?)

Timing Belt - REMOVAL & INSTALLATION
Although
timing belts may last for thousands of miles past the recommended
replacement interval, they should be replaced every 60,000 miles to
prevent trouble or damage should they snap. Timing belts do not usually
give an indication that they are worn or aging without removing the
cover(s) and inspecting the belt. A worn or damaged belt could give out
at any time. In some cases, should a timing belt snap while the engine
is running, damage could be done to the valve trains or pistons
requiring a partial or full engine disassembly. Also, should the belt
go when the vehicle is far from home, a costly tow or even more costly
repair job and considerable inconvenience may be suffered.
Timing belts must always be handled carefully and kept completely
free of dirt, grease, fluids and lubricants. This includes any
accidental contact from spillage, fingerprints, rags, etc.. These same
precautions apply to the pulleys and contact surfaces on which the belt
rides.The belt must never be crimped, twisted or bent. Never use tools
to pry or wedge the belt into place. Such actions will damage the
structure of the belt and possibly cause breakage.

(see Figures 1, 2 and 3)
The engine must be removed from the vehicle for this procedure to be performed.
Inspect the timing belt for signs of cracking, abnormal wear and
hardening. Never expose the belt to oil, sunlight or heat. Avoid
excessive bending, twisting or stretching.
To install:
Once installed, there must be not slack in the timing belt. The belt teeth must be in perfect alignment with the gears.

Hope helped with this (remember rated this help) Good luck.

Sounds like your idle air control, or IAC valve. Take it off and clean it out with some brake cleaner. Carbon deposits and gunk can build up and prevent the IAC valve from operating properly, by causing it to stick. If cleaning it doesn't work, you may have to just replace it. It happened to me on my Sentra, tripping my check engine light, sputtering hard, idled crazy, no power, etc. But once I cleaned it off, it ran so smooth. You'll need to get a replacement gasket, though, or make your own out of gasket paper.
