Attention: TDR Forum Junkies 
To start off, "Commonwealth Dodge" in Louisville, Ky. gave some real good service, and was real nice to me. Terry McKinley, their service manager, helped me a bunch!.
I was headed for Louisville, Ky. to pull some trls. from the RV show to dlrs. in Florida. I stopped in Warrenton, Mo. to get a coffee and use restroom. When I backed out of parking spot to leave, it would not respond to pushing the throttle, no lights or anything, just no rpm. , got out opened hood, could not see anything wrong, got back in and it was ok, it was midnight then, and thought it was just a quirk, and was in a hurry, so went on down the rd. Got east of St. Louis, getting off of I-255 on to I-64, It did it again. This time the check eng. light came on, and I got the P-2121 code. Thats when I called Mark Kendrick to find out what the code was. After setting there about 30 min. it started working again, so I headed on to Louisville. Spent the night in Habstautd, In. , next morn. light was still on, but everything worked just fine. Got to Louisville, checked into Motel, and found Commonwealth Dodge just a mile away. When I got there the eng. light was off. They used their diagnostic tool, and found the p-2121 code, called Star, and they would not do anything, because the check eng. light was not on when I got to the dlr. This made me very angry, but the dlr. was not at fault. BTW the p-2121 was low voltage to the APP, or TPS. I knew there would be Dodge and Cummins reps. at the show, so went there. There was 4 DC reps. one engr. and 1 Cummins rep. there. The DC reps just looked at one another, and the Cummins rep. at least talked to me about my troubles. I told him I had 2 trls. to deliver to Florida, and one was a $90,000. 00, 40' prototype. I told him if I'm going up Mt. Eagle, and my trk. quites on me, and the trl. is damaged, something is going to hit the fan, and someone will get sued because Star would not fix my faulty trk. Finally the Cummins rep told me they were having problems with the 03 TPS, that it needed to be blown out, cleaned, and dielectric grease applied, they were getting moisture in them. He took my VIN, and told me to go back to the dlr. first thing in the morn. I got there at 8 am, and was met at the door by the service mgr. , and was told that he had a message from Star that a new sensor would be there by 10 am the next morn. It was there on time, they got me out in about 30 min. and everything is working fine for the last 4800 mi. It has 21,610 mi. so far, and is still getting stronger.
Sorry this is so long, but it made me feel good that I rattled "Star's" cage a little.

)but I wonder if this is related to why my check gages light has flashed on and off before. I got over 8000 and it has done it 6 times. They can't find anything wrong. Last I heard they were waiting on a tsb from DC to tell them what was causing it. From what I have read on here there are a few trucks that have had the check gages light flash and some times you get the ding dong. Have to go back to the dealer today to get something they ordered for me and I will ask if they know anything new.
