while driving my hemi charger with the hammer down i suddenly had to brake and accelerate again, however at that point it wouldn't respond to the throttle and the tach jumped up and down but the car did'nt want to go at all. In fact I had to pull off a highway and stop(not shut off) and take off again, now the check engine light is on. This happened a day ago and after a few starts and drives the check engine light went back out by it's self and the car seemed normal. Does anyone have any knowledge of this or just an educated guess? Sure puzzles me! I'm thinking a speed sensor or possibly the ESP sensor? Is there such a thing as a limp mode as i've heard of and is this the cause, maybe?
i have had this same exact problem with my daytona. After a couple visits to the dealship they were finally able to replicate the problem with the computer plugged up. They told me that 5 star (dodge) is aware of the problem and they are working on a TCM flash to fix the problem. They said the problem is in the TCM and that a reprogram will fix the problem. This only ocurs when you accelerate hard and get totally off the gas right before the tranny shifts. The car "stumbles" and the TCM interprets a problem and goes into a free ride mode, which is basically just neutral. As soon as the car coasts to below 30 mph the TCM allows the vehicle back into gear. Obviously the CEL is set off but the only code it will show is 0700 which is a generic TCM code. Please let me know if you hear anything different concerning this problem. I will keep everyone posted as well.
See my post from today at the "Charger just shuts off in gear while I'm driving!!" thread. I'm the last one on page 25 or 26 I think. I don't feel like retyping all of it, but I've experienced similar problems.
I am very sorry that you have had so many problems with your charger. However it does seem like your problem is a little wider is scope than the one previously mentioned on this thread. I have never had my car hesitate at a light. The only time it does it is when I get on it pretty good and then get off right before it shifts. The best I can figure is because of getting off right before the tranny shifts for some reason it misses the shift. I have spent alot of time playing with it and I am 100% sure that I can now prevent it from happening by altering driving habits, it is not a good idea anyway to let off the throttle so fast after getting into it. But these cars get up to high speed so fast when passing people. Your cruising at 60 and go to pass someone and by the time you look down at the speedo your pushing ninety so the natural reaction is get off the gas but if you just slowly let off and allow the car to shift properly it wont happen, ever. So I will just drive responsibly and wait for the tranny flash to be developed. PS My wife doesn't get into it as much when passing people and she has never had this particular problem happen to her except when we first bought the car and I took her out and told her to really get into it so that she could get a good feel for the car and what it would do if she ever really got into it. Well for the people asking earlier my car is the 06 daytona top banana number 1229.
