SES light keeps coming on?

[DA BOLT]

Hey guys, my ses light keeps coming on and everytime I try to see what code pops up with my Diablo Sport tuner, it says no trouble code, I then clear trouble codes and it pops up the next day or two.

Anyone has any clues?:shrug:

PS. The truck drives normal and this has been going on for nearly a year.

Predators suck for pulling codes. Go to Autozone and have them pull the codes and let us know what codes you come up with.

only code that I have seen that it has a prob pulling is a rich code for banks 1 or two....

I am going to go ahead and say you probably have a vacuum leak. I am also going to go ahead and say it is your PCV connection to your lower intake. Just had this problem about 2 weeks ago. Got a SES light used the Pred and nothing. Cleared the codes and they came back maybe a week later. Tried again and got lean codes in both banks. Seems like those mystery codes like that always turn out to be a vacuum leak somewhere.

Thanks for the hints guys, I will look around for vacuum leaks and try Autozone if I don't find any.
