Had my Jeep for a few months. Had it tuned up, but had to get GM hoses to replace the old GM parts that were there so it would match up. Having some minor issues now, ordered a coil, but it had to be a GM coil to match up with the GM distributor. The guy even told me today that there weren't any Jeep parts on it, mostly GM. How can a Jeep (Chrysler) support parts from another make (GM)? Has anyone else run into anything like this?
