Hey y'all. I've got an 89 fitty with the 2.0 and 5 speed. Absolutely no power and bogs out severely, when you turn the key off it does that funky ain't gonna die tries to keep running and clattering. I know the issue when you turn the key off is usually timing on the v8's but I haven't had a 4 cylinder with a junky mikuni do it. Possibly the carb on both issues or a little carb and timing?
