Got my KS chaged yesterday and I am still getting a CEL but w/different codes. The cars stalls when put in reverse and tries to stall on the hwy. If feels like a tranny problem but everything feels good when accelerating it's only at cruising speed does it shudder or try to stall.

 

Hey man, I got a CEL code of 0413 also. There is no such code listed anywhere. Car runs beautiful and I reset the CEL light a week ago and hasn't come on since. Hey, I ain't complainin'.
