Hello, my name is ***** ***** I'm here to help get your problem solved.

Expert:  Dan replied 20 days ago.

This is usually a symptom of a clogged catalytic converter. You can completely remove front oxygen sensor from exhaust and if that allows rpm to go past 2000 you know the converter is clogged and needs to be replaced. Let me know if you have more questions or if there is anything else I can do to help. Thanks.

You will need to determine if it is fuel problem or oil problem, either could cause converter to clog.
