Hello and welcome to Just Answer! I'm sorry to hear you are having this problem. Let's work together to resolve the issue. Is the check engine light on and if so have you retrieved the diagnostic codes?

I received a code for rocker arm sensor stuck on bank one but I changed the sensor
Automotive Expert
OK, depending on the rocker arm it may have dumped a lot of fuel and damaged the [catalytic converter](/topics-catalytic-converter-honda/). Can you remove the upstream [o2 sensor](/topics-o2-sensor-honda/) or down pipe of the [exhaust](/topics-exhaust/) and see hot it then revs?

Will try that now
Automotive Expert
ok

Is this a common. Issue with the Honda motor?
Automotive Expert
It happens alot if you have massive amounts of misfires and yes, more in hondas and toyotas

Yeah it won't rev past 4000 rpm it hesitation and the gas pedal is not responsive like it should be
Automotive Expert
Did it improve with the exhaust down?

I need to get a special took to take the o2 outTool
Automotive Expert
OK, just let me know and well go from there
