i recently install test headers and test pipes and at first the SES light dint turn on after like 50mi turned on so i did some research here and did the non fouler fix but the light keep turning on every 5 to 10 mi i have reset the ECU and everything after the headers and test pipes and the non fouler install plz if someone can help me this would be appreciated btw sorry for any bad spelling

 

sometimes the non foulers dont work.

 

my check engine lite has been on for months now because of my test pipes its the downside of having it u have to learn to ignore the check engine light
