Hi,

The first thing we need to do is check for diagnostic trouble codes. What you described can be caused by a few different things.

This vehicle has an OBD1 system that doesn't require a scan tool to retrieve code. All you will need is a short jumper wire or even a paper clip.

Follow the directions in this link and let me know the results:

Take care,
