My honda elemnt was running fine yesterday morning. I went to drive home yesterday and all of a sudden it wouldn't rev above 3000.when it hits 3000 it spotters and jerks. Can anyone help me out? The only thing I change what TPS.

 

welcome to the forum. possible things could cause this. vtec pressure switch/solenoid,(be sure to clean the screen) bad throttle position sensor, dirty or bad mass airflow sensor.
