I am the owner of a 1986 CJ7 I had everything rebuilt carburetor generator radiator blah blah blah put in a rebuilt motor I purchased. Wasn’t happy with carburetion so I added a Howell electronic feel ignition system . Now it runs great spontaneously it will start acting like it’s starving for fuel, check engine light coming on permanently or flashing at different times I can pretty much always do the speed limit and drive it but it will not always perform well
