So guys and gals i have a question about a 2005 Dodge Magnum. It has that pos 2.7 v6 that chrysler put in everything. About a year ago it overheated on my daughter. Thermostat housing froze. Replaced that but still used water. Head gasket i think. I put a can of block seal in it. Seamed to work. Now chk engine light came on. Hooked up my handy code scanner. #2 injector misfire. Replaced it runs fine. Now has a top end rattle. Pretty nasty. But it comes and goes so i dont think its nottom end. But while its running it just suddenly shuts off. I have loaded a video for u to look at. And when it shuts off thats not me shutting it off. Just does it by itself. It will restart though. Any ideas would be appreciated. It has 221,000 miles on it. Im gonna have to done load the video on a separate thread. It will be next. Sorry
