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.
What happens when you go over 4000 rpm?
The engine computer has a built in rev limiter built in to the programming that will not let the engine go above 3800 to 4000 rpms when the transmission is not in gear and driving down the street. This is a normal protection so you do not over rev the engine and damage it. Was this answer helpful? Thank you for your feedback! Sorry about that.
