ok, i took my ALL STOCK tsunami out today and ripped this baseball field up. truck held together all day and ran a temp at idol of 212 at the highest temp was 239 and i ran this thing hard,at the end of the day i noticed that out of the muffler it looks like something melted like filter wire or something of that matter ,truck all of the sudden had barley no power ,the engine will rev up when i give it gas ,but the truck would barley move ,anybody know whats wrong with it? .......p.s. i did loose a screw that cause the right front dog bone to come out so i ran a 2 wheel drive for a little while and the end of the day ,think this could be reason for sudden loss of power?
