I am getting a SES light with a P0430 code. I recently did a fuel system cleaning at a local Strauss Discount Auto. The light came on shortly after this.

The car has Cali emissions and the comp has been reprogrammed by the dealer after the light started coming on.

Could this problem be caused by residuals from the cleaner? Do I need a new Cat? Any help would be appreciated. Thanks all!

 

Really need your help on this one guys, the Cali Cats are not cheap. Any previous experience in this area?

 

the fuel system tratment shouldnt mess up the cat. if it did the place that did the cleaning is fully responsible. most fuel system cleaners are O2 sensor and cat friendly, so i would look elsewhere. how many miles are on the car?

 

The car has 81,600. I called Strauss and they told me that the cleaning may have triggered the SES and to wait a few cycles (of fill ups) to flush the cleaner and carbon out. Sounded good to me, what do you think?

 

well i have the SES light on .. i put in the cleaner to get rid of it.. it worked in the past, well it has been three tanks of gas and the light is still on im sick of looking at it so im gonna go get the code cleared from autozone.
