An engineering disaster!
I'm another victim of the engineering nightmare that is AFM/DOD, (Active Fuel Management/Displacement On Demand). After only 125,000 miles, my Camshaft was destroyed, which in turn took out lifters as well. I decided to do the repair myself, mainly because I couldn't afford $6,000-$8,000 to replace the engine, or $5,000-$6,000 to have a shop do the repair. It still cost me a little over $2,000 in parts and supplies, ($320.00 to have the computer reflashed). When I did the repair, there wasn't a chance in hell that I was going to rebuild it with the same mistake that GM did, so I rebuilt it without the DOD system. After I completed everything, the truck purrs like a kitten, better than it ever did. I am so glad I got rid of that engineering disaster, I still think GM owes me, and a lot of other people as well. Can you say, CLASS ACTION LAWSUIT! I know I can. Thanx for nothin' GM!
