B16A struggling to rev past 3k
I have a jdm b16A in a 1999 civic DX. The car is throwing code P1259 for vtec wiring and a code for o2 sensors. Today the car struggles to rev past 3k but will if I floor it in first. I recently changed the spark plugs also. It hasn’t rained.
Fix the codes and it should rev normally. Post the O2 sensor codes.
