I get a call from my best friend 180 miles away at 6 am this morning. Naturally he has borrowed my truck. "It throws a code and falls on its face. It also pops when it does it. There sounds like there is a miss. " P2149. Quick thinking me (at 6 in the morning???) gets on the internet from my pda and search tdr. Multiple hits with the word "TST" attached to most of the threads. Calling him back, I tell him to check all the connectors for the injectors. He finds two of them loose. Truck running great. Thanks again to the people at TDR for hosting such a great website. And thanks to the joes out there for posting great helps, even when a person is 180 miles from their truck!!
