my poor little ranger is still running like crap. let me give you some background. its a 94 with the 3.0 with 96k on the clock. its had a tuneup within 5k miles.
i keep getting a code 332 (EGR valve opening not detected) and 335 (PFE or DPFE sensor voltage out of Self-Test range).
the DPFE sensor was replaced about 2 months ago. this straightened it up, for about a month. now the truck is running horrible again. when driving the truck, it feels like a trailer hooked to it jerking it back and forwards. it has a really rough idle as well.
i found this link that was posted by Meisk5, and it describes the symptoms exactly.

today i removed the EGR and inspected it. i used a vacuum pump and the EGR valve seems to be functioning correctly. i cleaned it up the best i could, as well as the EGR tube, and where it attaches to the intake. while in there, i went ahead and cleaned the IAC and throttle body. the EGR vacuum regulator solenoid was swapped from a vehicle with a properly functioning EGR system, but it didnt change anything.
i have done some reading here and have read that the DPFE sensor is a common failure, but i found the link above about misdiagnosing the problem, and looked into the EGR further, and still no avail.
my next step is actually checking the voltage of the DPFE sensor with a multimeter, and use a vacuum pump to check the vacuum lines for leaks. the trucks pretty quiet, and i cant hear any leaks, just the fuel injectors firing.
it could be the DPFE sensor again, but it had to be ordered last time because the connectors werent the same as the one the part houses list for the truck. if they really are a common failure like i have read, this is going to get old fast. i just think its something else causing this.
if anyone has any advice, tips, things to look for, i would GREATLY appreciate any help. thanks guys

. ill have to check it this week to see if the code is still there, and get back to working on it. i had forgotten about it until i seen this thread.
