Why does my car sputter at 4000 rpm?
The catalytic converter or muffler could be plugged up causing the engine to create too much back pressure and when the engine is running at 4,000 rpm’s, the pressure could be too high. Check the exhaust at idle with something covering the pipe and again at 4,000 rpm’s and see if the pressure drops or stays the same.
