94 Ranger Help
I have a 94 Ranger with 68,000 miles on it that is giving me some problems. I had the truck checked out a EGR low voltage sensor code was listed. I have replaced the DPFE and EGR valve and the EGR vacum control Solenoid.
The truck stills idels rough like it wants to quit. When I plug the vacum line going to the EGR valve it will idle fine. Also when the truck is cold it runs rough, once the engine is warm it runs fine. The voltage to the DPFE was 4.95 volts. I also checked to make sure the passage on the intake from the EGR was open and clear, and it was. I also checked the pipe from the EGR to the exhaust pipe and it was ok.
Does anyone have any idea what can be going on here? I am going to try and have it checked with an engine anylzer today.
Thanks

Welcome to FTE!
Hmm, sounds like you've been are all over the EGR system, it's hard to think of anything you didn't do. Honestly off the top of my head I can't suggest anything specific for you to try, what's left seems only to be maybe a faulty wire/circuit somewhere or a bad PCM. However, the following links might help provide you with some more insight and ideas:

Troubleshooting the Ford DPFE/EGR System
Good luck.
