Hello, my name is ***** ***** I'm here to help get your problem solved. If it runs fine up until 2400 rpm that is a symptom of a clogged catalytic converter. Completely remove front oxygen sensors to relieve exhaust pressure, if this allows rpm to go past 2400 you know converter is clogged. Let me know how it goes or if you have more questions, thanks.

Removed o2sensor no difference what next?

Try to see if you can get rpm up higher if spraying fuel into engine at same time. I'm assuming check engine light is not coming on?
