my 86 bronco 2 will idle but not drive down the road(engine dies after about 100 yards)
I developed a fuel leak and replaced the rubber hoses from the forward most "quick connect" connection. after this repair the vehicle seemed to run normal, within 2 weeks while driving it seemed to cut out momentarily, progressively getting worse until it quit while driving. got towed home, let it sit for a few hours and then got it restarted, let it idle in my driveway for an hour and a half, tried driving and made it 100 yards then it quit. any ideas????.
There are any number of things that could cause this, ignition module heating up and goin open shutting down the spark, distributor pickup coil can also do the same thing, fuel pump overheating when a demand is placed on it and shutting down fuel supply, restricted exhaust, will idle fine but when power demands climb it can't get rid of the exhaust fast enough so it starts to loose power and then dies. Have you tried getting the codes? That would be a good place to start.
