Around last fall I went to ohio on a camping trip with my buddy and his family. I live in maryland and on my way out my brother and I heard a light knock sound. We thought it was the CD in the radio so I backed the song up and then we didnt hear it. Then we heard the worst sound come from the engine
. The knock followed the beat of the engine but, very loud. I looked out my mirrior and the cars on my right slowed down because they couldn't see. White smoke poured out of the tail pipe and I pulled off the first exit
. I called onstar and they ran a engine check and it came up good. So up the road we went and bam the noise was back
. I had to pull over again and found a truck stop. After dumping a bottle of fuel additive in it, it never made the noise again. When i made it home I called the dealer and he told me it must have been a small piece of dirt in one of the injectors and that the bottle of additive lubercated and cleaned it out. He said I did no damage and it would be ok
. Could that one case be a early sign of the famous injector failer? My truck is a 02 D/A 3500.
