    get catalytic converter checked out. May be clogged.

    The diagnostic test will help pin point the problem. Also have them check the engine oil for contamination. You should stop driving the car until you have solved the problem since the gearbox clutches will cease. Had the same problem and ended up having the engine cleaned and the throttle sensor replaced. Now my car runs like a new engine.. Good luck

Why does my 2005 dodge ram 1500 3.7 liter only goes up to 4000 rpm when i reve it up and it starts to sputter when in park?


its the rev limiter. its suppose to do that when the engine has no load or the vehicle is stationary so you don't break the engine. now when your moving and it happens check fuel filter, fuel pump, air filter,etc.

check your TPS throtel position sensor. and the vehicle has a rev limiter so it wont over rev n park and nutral. but thats the first thing i would check do to many TPS's wear out and can get dead spots in them.
