is your car still under warranty? if so, it would be good to bring it into a dealership.

You need a knew:
knock sensor
TPS sensor
MAP sensor

Is this an ep3, rsx or rsx-s? I can give you links to the parts you need if you tell me that. All these sensors are pretty straight forward to replace except the knock sensor. The intake manifold needs to be removed to get at it.

ep3.

TPS - http://www.clubrsx.com/cr/OMN-TPS-RSC-p-ETPS.html Before you order it verify with them that it will work with an ep3. Im 99% sure it will but doesnt hurt to check.

I have just told you and given you links as to want needs to be replaced!!! The sensors are toast. How many miles do you have on the car? The dealer will only sell you the entire throttle body with the TPS sensor which sucks. That is why I linked you to the clubrsx site that sells an aftermarket Omnipower TPS sensor.
