great forum you guys have here. I have an 89 Wrangler with a straight 6 and recently have been experiencing periodic engine shut-off. In essence, the Jeep will literally shut off while I am driving and then turn back on again (assuming that is happening because I'm basically pop starting the thing as I go). Occassionally, when I start her up in the morning, the engine will idle normally then just stop...at that point, she will not start for a while, just turns over. I noticed I wasnt' getting spark at my plugs, so I started replacing stuff - New Coil, New Capacitor, New Distributor cap, rotor and pickup. Still no change. What else is there within the electronic setup that could be causing this?? Thanks in advance.
