CEL Code - P2098

drentooth · 04-24-2019, 12:24 PM

CEL came on today and found code P2098: indicates the PCM detected that the bank 2 lean correction limit for a condition causing a rich air/fuel ratio was greater than the maximum allowable limit.

- Post Catalyst Fuel Trim system too lean bank 2

...Never had this code before but I'm suspecting it's because of my HFC had it installed 4 months ago. I daily the car. I also have Stillen CBE. One of the guy I go to meets told me to install Spark plug defouler for the O2 sensors and should fixed the problem. Anyone had this issue before?

Defouler sounds like a good choice.

If you plan on getting tuned, the tuner can edit the A/F ratios and or stop those codes from popping. Used to happen to me after test pipes went in and tuner got the ratios right.
