I have an Acura RSX '04 with well over 100,000 miles on it (I commute about 80 miles for work each day). The engine light recently came on, so I panicked and brought it to the Acura dealership, where they charged $149 for a diagnostic. (Learned my lesson - bring it to a local mechanic next time.) One code popped up - P2647 - rocker arm actuator system stuck on bank1. VTEC issue. Replace oil pressure switch.
By the time I brought it to a local mechanic, the engine light had turned off. I've had 2 start-ups since then and it's still off, car is running fine. Should I still take it in and replace the oil pressure switch for $210? Or can I wait on it without any further damage to the engine? What could the problem have been?
