how bad is it....
codes-
p0160- 02 sensor CKT no activity- bank 2 sensor 2
p0300- random/multiple cylinder missfire detected
p0405 x2- EGR flow sensor A circuit low input (whats the double code about?)
p0410- secondary Air injection system malfunction
p0134- 02 sensor CKT no activity- bank 1 sensor 1
i have no rear o2 sensors, AIR or EGR. so i see why i have those codes but the missfire, im wondering why i have that. i do have a cam 228/228 114lsa if that has anything to do with it
