DOD killing my L76 2008 Vortec Max – Help!

[jaredlucky16]

Clogged cat sounds correct

Final Update... I Hope... The right side Cat was melted (side I had the lifter go bad twice) and the Left cat was starting to clog. I guess the cats didnt like driving on 7 cylinders for 3 weeks... I dont know if I will ever get to to bottom of why the #4 DOD intake lifter locked down and stayed down twice but as of now I got a Diablo Predator and programmed the DOD/AMF OFF.. Everything seems good to go.

 

Thanks for all your input..

Try NAPA. They were 1/2 the cost on my 2000, 6.0.
