03 civic si check engine light problem
I just bought a 03 civic si. The check engine light has come on 4 times in three months. Code p1298 & p0420. P1298 is electric load detected. P0420 is Cat below normal level. When I reset them, they both come back on. Just wondering if it's the cat or downstream O2 sensor...Any ideas?
