Common issues on these trucks. I just looked at a 89 with a stumble. The rad was replaced and the EGR valve was unplugged...the stumble dissapeared, but at the expense of the ecu turning on the check engine light at cruising speed in gear. Also this is called TBI (throttle body injection) a quick google of TBI running rich came back with lots to check. GL
