I have a 86 Ford Ranger, the motor skips when it <br>warms up. It has a 2.0 4 cyl. 1 barrel carb.<br>I've put on the following parts:<br>Rotor button<br>Dist. Cap<br>Plug wires<br>Plugs<br>Air filter<br>Fuel Filter<br>Fuel Pump<br>Ignition Module<br>Checked the timing, and for vacuum leaks.<br>The truck still misses and back fires.<br>When you go down the highway at around 65,<br>it acts like on of the plugs or plug wires<br>are fouling out.<br>I checked the EGR valve, it was stopped up<br>on one side, but I cleaned it out, the diaphram<br>works when you put a vacuum to it. Sometimes the<br>skipping will stop after you stop at a stop light<br>or cut the motor off, but it will start missing<br>again after you go down the road a block or two.<br>If any one has any ideas I could gladly use<br>some advice!<br>Thanks!

As I was advised here a few months ago, go to fordranger.com and pull up the 4 banger tech page. Post your question there and you will have an answer instantly. It is a great site..you will see many posts from me there as well as lots and lots of other people with varied backrounds.<br><br>good luck
