Welcome to 2CarPros.

Here are the steps that I believe should work on a 1990:

_____________________

Turn the ignition key to the run position (engine off)
Within 5 seconds, press the accelerator to the floor 3 times.
Wait approximately 5 seconds and turn the key off.

___________________

Let me know if that works. If not, I will look further into the reset process, but that should do it.

Take care,
Joe

If lights goes off while accelerating and comes on when not accelerating. Could it be low fuel pressure?

Welcome back:

Is it a check engine light that is coming on or a maintenance light?

Let me know.

Welcome back:

If it is the check engine light, you need to have a scan tool to reset it. That isn't a service reminder like I originally thought.

Welcome back:

I have to be honest, I don't have the technical information needed. However, have you checked fuel pressure and have you checked to make sure there is nothing partially plugging the catalytic converter?
