I recently wrecked my 2004 dodge 1500 with a 5.7 motor and I swapped the motor to a 2002 dodge 1500. Pulled the 4.7 out of the 02 and put the 04 5.7 motor in it. I have came across a big problem and need some advice. I have bought 3 different computers and even spent $250 to try to reset my computer. After I swapped motors it cranked and ran but no throttle control, I can push the throttle all the way down and it won't rev up and idles very bad. I bought a 03 ECM and it would rev up but when rev it would go dead. Bought a 04 5.7 ECM and it idles bad and no throttle control again. Place says my computer isn't fried but I can't figure out what could be going wrong...any help would be appreciated.

 

5.7 has fully electronic drive-by-wire throttle. You did swap that over too, right?

 

Did you train your TB? Google it. Something along the lines of pushing the gas peddle all the way a few times.

Train TB
Turn key to on but not start. Push pedal smoothly all the way to floor. Turn off key.
