Hello all, Let me first start by thanking the fellow list members for their ideas and suggestions, they proved very helpfull. And to your credit My D is running much better. I stated by checking th fuse box and cleaning off all the fuse conections, then I cleaned the connector to the O2 sensor, the Coil (which is a new MSD coil) connections, and the alternator connections. After being told that the DeLorean mufflers have a 0% failure rate I decided to further invesagate the exhaust system, No rust holes were noticed, so I decided to see if there was any movement in the exhaust pipes. What I discovered was a complete shock to me, the converter had unbolted from the Y pipe, after checking the gasket I reconnected the coverter to the y pipe. At this point I decided to start the car and see how she was running. At first she still ran a little rough, but after some adjustments to the timing and idle, she ran like a champ. The ducy alternator will be the next to be replaced since she still runs rough when both the lights, cooling fans and defroster are running. Both myself and 4194 thank you, for your help and advice Andrew 4194
