What the heck was THAT??
From : jmc
Q: this is something that has happened maybe 5 or 6 times over the life of my 2001 dakota 4x4 4.7l v8. normally this happens if ive backed up and nearly stalled the truck pilot error. did it the first time during the first couple of hours that i owned it then didnt do it again for nearly a year. this time it happened in heavy slow traffic starting to move out from a stop. it doesnt throw any codes just still has the p0455 which i have to do something about someday evaporative emissions leak; ive replaced the gas cap. what the truck does is essentially nothing i give it gas it gives me nothing sometimes a very weak attempt to rev just anemically tries but doesnt quite stall. the only way to get the truck moving is to shut it off then back on then it works fine. im guessing something in the computer gets confused but im wondering if anybody knows exactly what is happening and if its fixable. because its so very intermittent like i said maybe 6 times in 5 years ive never tried to take it to a dealer. doubt this has anything to do with it but the previous day we had a very exciting morning driving through a blizzard in the scottish highlands glencoe and rannoch moor for those who are familiar as the only vehicle on the road it was closed at both ends we found out later after we got by all the stuck vehicles. quite a bit of time in 4lo on unplowed roads and some 4hi on very iffy footing. was the most 4x4 ive ever done in this truck. had a lot of fun though. weather was so bad we spent an hour waiting to get off the moor because the snow plow itself got stuck! jmc .

im not as familir with the 4.7 01 dakota but does it have fly by wire if not suspect tps if so suspect its replacement a larger tps that has motor control of throttle functions. what you describe is exactly what i got out of my 00 cummns ram when the apps tps wiring harness was loose. -- max there are four boxes to be used in defense of liberty soap ballot jury and ammo. please use in that order. -ed howdershelt author this is something that has happened maybe 5 or 6 times over the life of my 2001 dakota 4x4 4.7l v8. normally this happens if ive backed up and nearly stalled the truck pilot error. did it the first time during the first couple of hours that i owned it then didnt do it again for nearly a year. this time it happened in heavy slow traffic starting to move out from a stop. it doesnt throw any codes just still has the p0455 which i have to do something about someday evaporative emissions leak; ive replaced the gas cap. what the truck does is essentially nothing i give it gas it gives me nothing sometimes a very weak attempt to rev just anemically tries but doesnt quite stall. the only way to get the truck moving is to shut it off then back on then it works fine. im guessing something in the computer gets confused but im wondering if anybody knows exactly what is happening and if its fixable. because its so very intermittent like i said maybe 6 times in 5 years ive never tried to take it to a dealer. doubt this has anything to do with it but the previous day we had a very exciting morning driving through a blizzard in the scottish highlands glencoe and rannoch moor for those who are familiar as the only vehicle on the road it was closed at both ends we found out later after we got by all the stuck vehicles. quite a bit of time in 4lo on unplowed roads and some 4hi on very iffy footing. was the most 4x4 ive ever done in this truck. had a lot of fun though. weather was so bad we spent an hour waiting to get off the moor because the snow plow itself got stuck! jmc .

fly by wire is a method of throttle control whereby you use your foot on the pedal but its not connected directly to the throttlebody. it operates a potentiometer which in turn feeds info to the pcm which operates the throttle among other things. the tps is on the throttlebody located on top of the engine. -- max there are four boxes to be used in defense of liberty soap ballot jury and ammo. please use in that order. -ed howdershelt author suddenly without warning max dodge exclaimed 3/17/2006 135 am im not as familir with the 4.7 01 dakota but does it have fly by wire if not suspect tps if so suspect its replacement a larger tps that has motor control of throttle functions. what you describe is exactly what i got out of my 00 cummns ram when the apps tps wiring harness was loose. im afraid i dont know what fly by wire is. can you tell me where the tps wiring harness is so i can check and fix if needed jmc .
