Hi @daytons ,

Check if there are any codes showing in the OBDI port which may give an idea of what is happening in the engine.

As far as I can find out your model has an OBDI system. (also known simply as OBD)

As best that I can find out OBDII came out in 1995 for your make and model, you may wish to verify this however.

Here’s a link that may be of some help on how to do this.

If it works and there is a code showing search online for what the code means for your year model vehicle.

Check the EGR valve and make sure it isn’t stuck open or closed, it can cause a engine light at highway speeds sometimes my 90 does the same thing
