Maff, did my heart good to see someone else monopolizing posting duties.
Time has come for me to head back to work. While out at the local cars & coffee yesterday, when I left I had some stuttering. It cleared up though. Then the exhaust was really loud. When I got home crawled underneath to find one of the bolts connecting the header outlet to the rest of the system had backed off. Tightened that up and it was fine. Then later yesterday when I went to run an errand, I again had stuttering when she was cold. First thing this morning I pulled the spark plugs and found coolant in cylinder 4 (again). Looks like the wife won't be driving her while I'm gone this time.
