High HC readings at idle....
o2 sensor? At 2500rpm the readings are fine. Everything else is within spec, just HC at idle(reads 204, limit is 125). Car was warmed up and I wrung it out on the highway for about 10 mins before the test-oil temps were high, coolant temp 75C or so. Any other ideas? Thanks!
