my truck just started this it acts like it has a rev limiter when it is not all the way at normal running temp. i can push the gas and nothing happens. i can kill it and re start it and it will run normal for a min. than it is craps out again till it is hot or 180. it acts like it is loading up, i can through it in neutral and floor it while smoke is coming out u cant even see behind the truck. please help... i have no idea what to do!!
