Throttle code problem
I have a 2004 Durango 5.7 Hemi Limited, the. Check engine light and ETC light are both on. Trouble codes are PO 642, PO 2122, PO 335 and PO 700. Cleared the code and PO 700 didn't show back up. My Durango is hard to start, has a ruff idle 1000 rpms to 1300 rpms press the accelerator and it will only gain 300 rpms no matter how much it is pressed. It as if the accelerator pedal doesn't work. I have replaced the Accelerator position sensor, crank sensor, air filter and Accelorator pedal with sensor. Anyone have any ideas?

I have moved your post to Duragno section for better answers, although it should be similarly diagnosed as a Ram.
P0642 Sens Ref Voltage 1 Circ Low
P2122 Throttle/Pedal Pos Sens/Switch D Circ Low Input
P0335 Crank Pos Sens Circ
P0700EATX Ctrller DTC Present
I would use a DMM and measure the voltage output at the throrrlw body when idle and when at WOT. Your engine does not have to be running, jus key in ACC.
You can download Service Manuals for a Ram in the FAQ section as they are esentially diagnosed the same way and have all same specs. I believe it should be around .7-1v at idle and 4.5-5v at WOT. Not entirely sure though.
