Hey all...I have a 2006 Ram 1500 2wd. Occassionally, I have this issue with what i believe to be the transmission, or something to do with the gear shifting computer. What it does, although it is rare, when I go over a rough bump, it knocks something loose, and my acceleration and just isnt the same. I get up to 50 mph and when i let off the gas, it kinda feels as though im applying the brakes, when Im not, it also does this jerking/bumping feeling, but it only happens when im the lowest gear, or overdrive i guess you would say...I took it to the dealership, and took the guy for a ride, but naturally, i guess i hit the magic bump and it knocked whatever was loose back in place and all is good now...so he couldnt say anything was wrong...if anyone knows what this is or has has a similar problem...please fill me in. Thanks...

 

Check the Throttle Position Sensor, it could be going on you or their might be a problem with the connector...
