Use the paper clip method if you can't find the scanner. It's quick, easy, and best of all....cheap! If you don't know, here's the link..

...For some reason your youtube link went to the main page and said your video was private...

...From your codes listed, I would do a search for EGR...

i logged of my account and clicked the link and it works

 

[Tbars4]

...From your video I got ...

332 =(R,M) EGR did not open/respond during test or if memory code, did not open intermittently - EVR or PFE

336 =(O,R,M) PFE sensor signal is/was was high - ">PFE

...Do a search on here by those code numbers and also search DPFE...

 

[KobeJ05]

332 C,R EGR vavle opening not detected

336 R EGR circuit higher than expected

...did someone say dpfe ?? :shifty_ey

can someone tell me what a dpfe is?

 

[boggs1227]

dpfe = dual pressure feedback egr

tho there was a "pfe" ( pressure feedback egr (( only one hose to connect the "dpfe" has 2 hose connections ))

cel?

I'm somewhat new to this board, when you say cel, do you mean check engine light? Cause I do have a question about one popping up on my Explorer

yes

I have the same/similar issue with my 94. While driving the cel light comes on and off randomly. I don't sense anything different while driving. It doesn't come on when the car first starts, but will after you start driving. Owners manual states that when it blinks it means whatever issue had occured is resolved. I doubt this. I've heard it could be an oxygen sensor, air filter issue (already replaced that) or fuel line issue. It doesn't blink but does pop on and off randomly

...The intermitent light informs you that you are having an intermitent problem...If you have a 91-94 X and a paperclip, it is time to read your stored codes...Check out the sticky here..
