[Aloy69]

Hello

I got silverado 5.3L 2012 Z71 i bought it brand new and use it for for 2 and half years with K&N intake black edition worked fine but now i got some problems:

First: it shows traction service and the traction lights r on .

Second: while driving my car sometimes gose off for 1 sec or less then bk on by it self ??.

 

When i took it bk to the dealer they checked and they say Its becoz of the K&N so i removed it but its still have the same problems.
