i have a code p0602 i lost my list of codes so if some one could help thanks

 

P0602 is an ECM fueling calibration error.


Since you have a Superchips tuner. That may be the cause of it! I'm not familiar enough with the Superchips products, but someone around here is bound to know and rest assured they will be able to tell you if that is normal with your product.

 

When I had my superchips installed I had no codes.

 

i tunded it back to the stock settings and no code yet i have hade the tuner for 5 months and no glitchs it feels like i lost some power in the upper RPM range so i scanded it for codes the power would drop off at 2 grand ill drive it stock for a wile and see what it does

 

my dad has an 02' and he had that code and his truck would like randomly die at a stop sighn then start up agian...turned out he needed a new ecm....he has an edge EZ on it to
