I don't know the '89 5.0 that well. Is it carbed or fuel injected?

Is your 'check engine' light signaling? That would be your best barometer. If your light isn't signaling, you could still have codes in your computer. Pull the codes, and see what they tell you. It could be an o2 sensor, TPS, EGR, you get the idea. Could also be your catalytic. Does your tailpipe put out black smoke when you start it?
