Hey guys I just bought a 99 sport 4.0l that has a miss in #1 cylinder I have fuel,spark good compression but I read about a bulletin from the Chyrsler Corp about weak valve springs causing the exhaust valve not to close all the way thus causing the missfire. My question is has anyone heard of or had to deal with this problem. I also have a 98 sport classic both are in great shape with no rust and run great except for this minor problem with my 99.
