03 accord v6 MT and my check engine light comes on and throws a p1077 code sometimes two of the same code, but when I wipe the code, it doesn't come back on till I go over 4500rpm. It drives and rides normal so idk this stumps me

 

P0661 and P1077 are both related to the intake manifold runner control actuator and solenoid valve; the mechanisms that switches between the short and long intake runners. The first code points to a problem with the position sensor and the second code indicates some problem with the IMRC actuator or solenoid valve or both.
