Hey Folks, my 02 4.7 4x4 Quad has a a few problems pop up in the last couple months.

1. Will not start when hot. Wont idle stutters and dies. Let it sit an hour starts fine or nail it with some starter fluid and rev the hell outa it and it'll run

2. No speedo, stalls coming to a stop some times.

Error codes

P0123 TPS Voltage Hi

P0500 VSS not found.

Decided to fix these this weekend, went to remove the VSS sensor on the rear end, and it came apart in pieces, Aha I say, got ya. had to dig the outer case out of the hole, installed the new VSS , disconnected battery and..........still 0500. Later in the day after a run to the parts store, I install a 2nd VSS and.......0500. Connections seem ok. Arrggh Fine I say, time for problem #1, wont start when hot

I thru the day I install, after a few trips to the parts store, MAP sensor, TPS Sensor, IAC motor, IAT sensor and finally 2 O2 sensors. PCV.

Problems Fixed=0

Still won't see the new Speed Sensor, Still has the 0123 TPS error and still wont frickin start when it's hot.

I'm a fan of the Dakota's, this is my 2nd, but I'm going nuts replacing all these sensors and fixing nothing. Oh give me the days of my 68 Ford.

Please save my sanity and relationship with my Dakota

 

I had a simaliar issue with a 97 explorer, try disconnection the brain and cleaning all the connections, I had to eventually change my computer and knock out my cat.
