CEL is on, said o2 sensor and dirty intake manifold?
Changed the o2 sensor brand new
its still on, saying the same codes
Is it cuz of the dirty intake manifold that the o2 sensor is on?

LMK! i think it might be

 

Bump! anyone?

 

There's a CEL for dirty intake manifold?

 

what year civic do you have an what exact codes are you getting?

 

lmao..!!

 

^This

 

98 CX Civic hatch
Well not for dirty intake manifold, but the guy told me to clean it up and the IACV and im thinkin it might be the IACV?
exact codes...hmmm damn i lost that receipt he showed me so no luck to get help there..

 

Have the codes pulled again. The codes are your best clues for getting specific help.

 

Aight ill head back to autozone and get a code checked, and ill update with codes
Hopefully i can get the CEL codes fixed!

 

maybe it's so simple that nobody has mentioned it, but did you disconnect the battery when you swapped the O2 sensor? because it you did not disconnect the battery then the ECU will keep the trouble code in it's memory, even if the engine is no longer throwing the code. to get rid of all stored trouble codes just disconnect the battery for a minute or so, then reconnect and check you check engine light again.

 

okay Ill try that too thanks

 

P0420 is the code from Autozone
Seems like it is the Catalyst converter
