You need to pull the diagnostic code and see where it leads. go to local auto parts store and most of them will help you to pull it. its where you start.

The check engine light comes on after i reach a speed of 45mph and then stays on but this only happens at speeds 45 and up

Have it scanned to see what the check engine code is. when the light comes on at speeds 45 and up is because it is sending unburnt fuel through the catylitic converter which can cause damage to the converter. have it scanned either at a repair shop or a parts store. the only problems at the parts store is that they can tell you what the code is but not how to fix it. they will just recommend parts to buy and try to fix it then after you buy a bunch of parts and still have the same problem only to end up at a repair shop that can properly diagnose and repair the problem but you already spent about three or five hundred dollars on parts you didnt really need.

Replaced clutch in 91 Trooper. Will shift through

Sounds like you put the clutch disk on backwards. Your not getting enough throw or you installed the wrong kit.

Distributor cap compatability

your caps should be fine between a 90 and 91 one thing you should also check is that the kanooder valve on a 90 is different from one on the 91 these would not be compatable they redid the duflage sensor plug that goes from the kanooder valve to the wiring harness. you might need a kanooder valve mod kit these are really cheap you can grab one from checker for about 20 bucks well worth it trust me.
