Exactly.


The later model years did not have this problem usually...the port was enlarged to a single port about the size of a dime or so to eliminate the carbon build up the earlier design had. It would take a lot of carbon to block it.

If the port/ports are/is clogged there will be no change.

P0402 Excesive flow will set for the EGR valve itself ...correct...but not always, a bad DPFE can set this code as well....
P0401 Insufficient flow usually DPFE, ports, hoses.....The 4.6 and 4.2's rarely burned the hoses, it 's more of a 5.4 issue. The picture you have Jbrew is for the 4.2 and 4.6's...the 5.4 use one similar to the one in the first photo however they are plastic for the 02 model year.

 

A bad DPFE is most likely what he has. Cleaning the Plenum ports first , as it could be the problem is better than just throwing parts at it AND it's good for the vehicle as well.

I have already posted there are TWO plastic DPFE's used . The OP did not post model year or engine size. I covered just about everything which you have failed to do.

You need to get a life and stop trying to pick my posts apart , it isn't working for you. Your not helping and probably confusing the OP for no good reason, other than striving to be a now it all = a$$.

There is nothing inaccurate about what I have posted . I suggest you try another site/forum, it would be to your advantage that you learn to be more considerate before doing so.

 

The DPFE on my 98 f150 went out a few months ago. It wasnt expensive at all and it wasnt hard to install. I went home and did it myself.

 

WTF dude I have done no such thing.
Have you ever heard of a PM?

Telling the guy to pull vac on the EGR and to replace it if it does not change the idle speed is inaccurate. Maybe it was your post that was misleading or confusing if not read correctly???? You cannot make assumptions on codes alone without proper diag...

Who gives a crap about who is more correct other than your ego...That's what PM's are for....Keep that petty crap off the board....I'd be glad to chat

 

Once again , you are incorrect . It might help to know what your talking about before you post. I'm not going to school you, your SUPPOSE to be a Tech

 

So you ae telling me if the EGR port are plugged shut you will get a response out of the EGR valve ???...A response to the motor on the feed side from the EGR to the intake???....you know ports we have been talking about????? Sorry guy......EGR has two sides....intake side and exhaust side....if the intake side is plugged it will not feed to the motor which in turn will not change the idle etc....Keep the personal crap to the PM's Jbrew...we can discuss credentials , who has bigger nads, time day, weather, whatever you like....keep it technical on the board....

 

What The Hell? I didn't say nothing about testing the Valve for port problems Mann, you are some kind of idiot. I instructed that AFTER he cleaned the plenum ports. Get your sh^t straight! The test I outlined was for valve operation and diaphragm testing after the port has been cleared/cleaned. Which then as said - is probably something he didn't have an issue with . Poppet valve/diaphragm failure is usually revealed after a PO402 has been set.

Yea , you are sorry sac - you might want to read a little slower and then tell me what credentials can possibly override the facts



I can't help that you can't read correctly or don't understand a simple process and what the hell does "Nads" or your "PMS" have to do with anything- you frickin weirdo

 

We test before we tear apart....knowing an 02 F150 (as you have suggested this may be) has EGR ports the size of Texas, taking the elbow off can be avoided to get to the root cause of the problem. I never said cleaning it was not a good idea, just that it was unlikely the problem.

Hmmm....that's your opinion, whatever...all I did was elaborate on your original post and your inflamed 8,000 something post ego took over...

No, you suggested....it is confusing like it or not. You don't take criticism very well do you?...the test you list is valid for the valve, I was just trying to make a point that clogged ports will give the same symptom, you sir did not make that clear at all....no need to be an A** about it.

What's with the personal attacks? I never said "Jbrew is an idiot and doesn't know what he's talking about blah blah blah..." I've tried to keep this thread inline with the problem at hand...other than your ego that is....Keep your comments to yourself, or is this what you do to make yourself feel better......Once again a PRIVATE MESSAGE aka ("also known as" since you seem to have a problem with acronyms...) PM would be more appropiate if you have an issue...or is sh*t slinging on a public forum a regular tactic of yours?

If you feel like you need to be the most correct person on here then by all means have at it...what do I know right?

 

I don't have a problem correcting inaccurate info if needed. If you aren't clear about something (my post) then ask thru a PM or here, it doesn't matter to me, except, it wasn't initiated that way now was it...

What's ego on the Internet ? That's overrating things a bit or just another assumption - I've been wrong before and admitted when I am. You misunderstood and went into a correcting/dictating mode and I didn't appreciate it. Plain and Simple.

 

Whatever...

I've seen how you reply when you think you are more correct than someone else...you're so keen on just the "facts" well thats all I posted in addition to your post, nothing more, nothing less...don't make it into something it is not.

Remember the 4.2 coilpack thread, telling Joshmac4.6 he was an idiot about the coils being paired????? Geez...freaking relax...seems to be a trend with you

I suggested you try the PM a long time back in this thread but you just had to keep ranting along about your superior technical advice and how I don't know what I am talking about....I'm done with this...take a chill pill and keep the posts on subject.

 

Yea , you are the two . You guys have to related . You guys join this site thinking your all that trying to correct everyone . Your a couple A-holes - both of yuh. You can choke on your "chill pill" and don't forget share it with your B-buddy.

Ha!! I see you sent your pal over to the "Other Powertrain" forum on this site. He or she's doing a good job over their cutting down Jordon not Mike - Who's another long time member of this site, who also has helped many in the past. Don't think for a minute you freaks are going un-noticed!!!

You guys, you two are pair all right .. Keep it up you piece of sh^t, your making as many friends as your buddy. I new you guys were related - it's transparent

 

Whats your deal?
Can't keep up so you have to resort to childish namecalling ? That's about your speed. Yeah you are a big help around here alright until someone contradicts you all mighty one......Would you like an updated DVD from Ford so you can keep up, I'd be more than glad to send you one......

What kind of insane rambling on is that?????I don't even know what you are talking about.

Like I said you can't keep it technical so you do what comes naturally to you it seems....who's the real jerk off here???? You are the one who needs to be taken back a notch...............

 

I'm handling it , thanks

I would suggest starting a new thread, if you have so many questions, or are that confused

 

Changed your mind from your original post I see....

So did I.........I don't trust you so just go on handling things.........
Maybe if you had not been such an a**

 

BTW go buy your own DVD's...readily available through the google search engine...............
