My name is Kirk and a few weeks ago I picked up a Red 91 XR2 complete with hard top. I had a 20 mile drive to get her home. About a mile from home it started running real rough but I made it home. I joined this forum to review all thoughts and ideas you folks have had on rough running Capri's in the past. So I starting trying some of these ideas. I put new plug wires on, new plugs in it, checked spark, checked timing belt alignment, I did the B12 Chemtool thing and the Seafoam thing. I checked compression which was good. A friend (mechanic for 26 years) came over to listen to it run and he said it sound like it may be out of time. We checked timing again, we looked over the Dist. Cap still no clue. He was about to run home a fetch him Injector pulse light to check injector pulse when he discoverd the problem. The large wire harnes the houses the injector wires and who know what other wires was looped down low and was rubbing on the left CV axle. Several wires were completly severed in two.Turns out number 2 and number 4 had no injector pulse. We pulled the battery out of the way so we could repair the damaged wires and now this 91 XR2 screams down the road again. This is the second car I fixed with chewed up wires. I just thought I would share this story so if you have tried everything don't forget to check the harnesses.
