Rich, did you get a chance to check what we talked about on the fix. Later JJ

Any news Rich? Are stuck somewhere?

Have the Stealer do an injector flush while you are there, it is cheap and the difference can be amazing.

We flush gas injectors.....replace diesel injectors. The early duramax injectors had cracking problems

05's have a problem with the injectors i thank it is 2 and 7 the conector will come loose and not make contect you can tweek the pins in the connector and make them work for a while if that is it there as a tech bull. out for this problem

more than likely an air leak especially if it just happened after changing filter . it is a good idea to stick with ac delco on this item and make sure to lube orings before installing. you can also try to uninstall your programer or module and see what that does I have had a few in the shop where something has gone amiss in the programing .one that installs in line as opposed to a program that is downloaded into the system is more likely to cause issues

Our local Stealer is doing a lot of GM recommended flushing 1st is @ 20,000 miles and $115.00

they're all manufactured by Racor. Pay out the azz if it makes you feel better.

wix is a plastic filter housing versus metal for the delco item

the only difference is the top insert that locats the filter media in the can, plastic vs metal. No performance or install advantage/disadvantage to either. The threads and o-ring seat are exactly the same as it is the same metal can.

all versions manufactured by Racor! GM just specs a metal insert/cap to locate the media.
