Hello all,

I am new to this forum and have found a bunch of great info. so please let me know if I am on the right track!! A couple of months ago my 92 F250 5.8l began to run a little rough at idle and low speed almost like it was missing but nothing consistant. It finally started to really bug me the past couple of weeks so here I am. Looking around here I have checked codes using the method at fordfuelinjection.com and came up with 1) Egr valve opening not detected 2)EVP circuit below 0.24v 3)DPFE or EVP circuit below 0.2v. With that said I think replacing the DPFE sensor would be the best first move, but have read that it can be electrically check but have no read how(??)!! I have replaced plugs, cap and rotor but not the wires yet( I know with a 106,000 they need to be replaced) It recieves regular filter maintenace. Just wondering if you all feel like I'm headed in the right direction???

 

no thoughts Come on guys, help a brother out, before I have to beg

 

check you i.a.c valve probably full of crap. check your egr passages as well.

 

If it were mine, being a 92, I would personally go ahead and replace the DPFE and EGR valve. Probably give the MAF a good cleaning too.

And CHANGE THOSE DAMN WIRES! LOL
