Your O2 sensor is bad and your car is running too lean. Retard the timing a few degrees and replace your O2 sensor.

CEL = automatic fail.

B20runner

how much will that cost?
and plz explain more abotu what tool lean is thx

jlacoy82

Timing = free
New OEM o2 sensor = ?? $50-60? I think. I dont know.

B20runner

ok so the timing has to do wit the too lean thing

dohc notec

the bad O2 could do it too. when you replace that clear the code and drive it like 60 miles before retesting so the cars readiness monitors can set.
