Hi,
This can be a few things. The first thing I suggest is to retrieve diagnostic trouble codes. This vehicle has an OBD1 system. It doesn't require a scanner to get the codes. All you will need is a short jumper wire or even a paper clip.
Here is a link that explains how to check for codes:

Now, if you find codes, let me know what they are. If nothing is found, then we need to start checking different components. First, confirm the fuel pressure is within the manufacturer's specs.

You will need a fuel pressure gauge to do this, but most parts stores will lend or rent one to you.

Now, a partially plugged catalytic converter can also cause this. Take a look through this link and see if it mirrors what you experience. Additionally, the second link explains how to test one.

Lets start with this. Let me know what you find or if you have other questions. Also, if you can think of any other things that may help me diagnose the issue, let me know that as well.
Take care,
Joe
