Still new to my duramax, LB7, that I bought back in like April. Truck has no aftermarket goodies on it, not a daily driver, and is taken care of.... not abused. Friday I drove it to work, because fuel is cheaper in Missouri than Kansas, and I ran into some BIG problems.
Got off work at 3:00 and drove the truck 3 blocks to the station. Filled up, and was on my way.... got to a stop light and stopped....... light's green and started accelerating. Got through the intersection and then another couple hundred feet and then out of nowhere....KNOCK KNOCK KNOCK and smoke just pouring out of the exhaust pipe. I mean, I couldn't even see anything behind me. Whipped it in a parking lot right beside where I was on the street and shut her down as fast as I could. It made, and still does make me sick to my stomach that this even happened. The truck was knocking really loud like a rod or something. It was really weird the way it happened under a normal driving condition.
Called a friend I know from the dealership I deal with, and he said it sounded like injectors, or something on top of the piston. Also asked him to run my VIN to se if the injectors had been changed under the warranty, and they were at 114,000 miles. My truck now has 169,000 miles on it, and ran absolutally fine before this. Crappy part is I had to get tailered home and leave on a vacation trip saturday morning til today, so it has been sitting in the driveway this whole time. Also, my friend at the dealership is out of town til monday, so it will be even longer til I know something.
All I know is that he said the injectors can go bad 25 times within 7yrs 200,000 miles and they'd change 'em 25 times under warranty. Not saying this is going to help me, but I was wondering if any of you guys had anything you think this could be, or something I could check considering it is going to sit at my house at least 5 or 6 more days.
Thanks in advance cause this sucks.
