walt I have a 1991 Ford Ranger w/2.3L . I went through the same problems changing parts out. mine was still doing the same thing. then I replaced the ignition control module fixed all the problems. I drive it back to and from work everyday and never had another problem out of it since then, hopefully this may help you try one from a junk yard first it may save you some money new it will cost around $150.00 fordman26
