Ok code junkies I need info plz
My car failed smog has a code 1153 O2 sensor or Ho2o.
Question is it also coded again with 1416 a few days later can that o2 sensor also create the 1416 code?
The car smells like it is running rich and does seem to idle a bit rough at times. Its going to RPM MOTORS Charlie on Friday I do have the #1 O2 sensor should I also get the HO2o sensor also just in case?
Thanks For the help

Yeah, the 1153 is slow/low response on a rear 02 from your header/highflow cat setup. Pretty common and can be easily edited out (I did it myself with HPTuners). It doesn't effect the tuning, it's just an emissions alert.
The 1416 is a stuck/bad Air Check Valve - basically it's a valve that prevents reverse airflow in the air system that's used to create cleaner starts (yet another emissions control). There's two valves (one per side) and 1416 is in a tough place to get to. Some people have had luck spraying some cleaner into the intake side:

Excellent step-by-step.
I'm eventually going to remove all this jive in my car - plug changes will be easier, etc., though I see from your location, you'll need to stick with all the OEM emissions equipment.
Good Luck!

I'm replacing the rear o2 sensor tonight hopefully it clears up the other code. It also coded the cat 430 If the stars allighn the o2 replacement will clear that one also. The car has a little over 1000 miles on the entire exahust system. Dynatech LT with their bullet cats X pipe and borla stingers.
Thanks again for the help... Then off to charlie tomorrow
