FORD WITH ISSUES. HELP
hello, I have a 1991 ford ranger 2wd. It has a 4.0 v-6 engine. The problem I am having with it is it hesitates when you take off and stalls at times. It also the idle goes up and down when it is just sitting in park or at a light. The check engine light will come on while driving it.,but goes back off when you restart it. We just replaced the fuel filter and plug and wires. but don't know what to do next. PLEASE HELP.........
