Hey guys, we did a dod delete in 2007 sierra 5.3, used the ams delete kit. The full kit. Put in and put computer to it. Been 3 weeks now and I've had a rough idle, engine light on one day and next it's off, as well stabilitrack randomly off and on. Looks for any help as to why? The guy who put computer to it, said they do that at first but will go away after a week or two

 

Check all connections and grounds. You did put in a non-DOD cam, right?
Does it run OK above idle speeds?

 

You need to verify that the tune took, that it was done correctly. What codes are you getting?

 

Yes, codes are key here. and I'll 2nd the question...You did change cams, right?
If so, the tunes wasn't done correctly or you have a intake leak.
