Sounds to me that your cat is plugged. Try unbolting the down pipe from the driverside manifold, and pull it down a bit. Then start and rev it up again. It will be a bit louder, but if it runs fine then you know you have an exhaust plug. I had a car that I got from my brother that did that.

91 trooper isuzu 4 cyl,runs bad when cold,where is the sensor/

The coolant temp. sensor is located under the intake manifold at the #1 intake port. It is not easy to access. Check the connector for corrosion.
It maybe accessable through the right wheel opening over the tire. Good luck

91 ford f150 will idle fires up easy but give gas and backfires multiple and keep holding gas it bacfires multiple bogs down and dieshas 1 vac line off cant locate where it connects

Not sure bout the vac line try looking in the back of the carb. The backfiring could be a timing problem. May be the timing belt slipped. Under the distributor their is a bolt that holds the distributor down. Loosen that bolt and try rotating the distributor either direction while the engine is running and see if it smooths out.

1988 isuzu trooper 4 cyl 4wd vibration

I actually have one of these myself that I drive daily! It is missing, several reasons for that, one plugs or wires, second these are notorius for headgasket problems and if it leaks can fould a plug. MIne did everytime it cooled down, but then after a few minutes it would dry out the plug and run ok. The wires and plugs would be my second check, the coolant level my first. These are great little cars and worth fixing in my opinion, I hope this helps you some, And Merry Christmas
