brew, see you like my new sig. Was playing with some photos and thought I would run this one for a while.

 

Yea , that's cool ..

I seen you put that one up from the Ford DVD that one time . When I seen it I thought - Where have I seen that pic before??

I thru that DVD in sometime later and there it was

 

Thanks jbrew.

i've been getting the expy ready for my stepdaughter to take to Houston.
transfered there recently
but that means she'll be out of that expy sooner and into a new set o wheels. i'll have a expy
i gota lower it though any reads for that/ i won't have to look for it so long

 

The result is in.

The throttle body was clean. PDFE was ok. The exhaust leak was from a vacuum line. Line is reattached and the engine runs like a charm. Thanks to for all of your help.

 

Idunno - prolly in the suspension forum . - Lower it ? They sit to low already - They could stand at least another 2" of travel.

 

Okay, I think my mechanic needs to be trained by Jbrew, or I need Jbrew to be my mechanic.

The damn check engine light is back on after 23 miles. All of the vacuum lines are attached and don't seem to be leaking. His boss is going to call me. I'll request that the TB be cleaned and have the DPFE rechecked.

Another suggestions (besides firing the mech or changing shops)? This is being paid by the dealership.

 

Continuation of the check engine light problem.......

Took it back to the shop and had it inspected. This time the computer found too much exhaust circulating thus causing a build up of carbon. The excess carbon caused the EGR Valve to stick. Can this happen?

The shop is backed up and I get it fixed beginning of next week. I have to admit, I'm not too familiar with fords. I can do some work, but is this a hard task? I'm grateful for any suggestions.

 

Yes , that's possible . Changing the EGR valve is purdy easy .

BUT - You need the get a Haynes or Chilton's Service manual for your model.


I think there still around $19 @ any automotive parts supplier. You'll be glad you did.

The EGR valve is that flying saucer looking ting under the hood.

 

I'd be willing to bet that the valve is okay (they just don't fail that often) but they pulled a P0402 this time (and that it was a P0401 originally).

I'll stick with a bad DPFE sensor. The factory ones from that era were crap. The new Ford replacement sensors are much improved to handle the exhaust environment.

Okay, new EGR value & replaced DPFE sensor, check vacuum lines and cleaned TB.....check engine again after 25 miles with . Insufficient air flow. Any ideas?

 

Did you use the latest DPFE sensor from Ford? Aftermarket DPFE's are junk.

 

When you say you cleaned the throttle body, you mean you pulled the elbow off the intake manifold and scrubbed the two little ports clean, right?

And you do have the DPFE hoses going to the right ports on the tube and the sensor, right? The bigger hose goes to the "HI" port.

 

Yes, I had the mechanic check and clean the TB. He "scrubbed" it out. He also checked and replaced the DPFE. He thinks it could be a ECM problem that he will have to send to Ford. Also one more thing he told me, that althought the truck is a 98, he had to use a EGR value for a 97. Has anyone ever run into this problem?

 

I never heard of that ?? - Actually , the 97 and 98 are just about , if not Identical under the hood.

EGR Value ? What does this mean ? Sounds like he's shoveling some chit at yuh . If your not doing things yourself - it's real hard to tell what he has done or not done . He might just be blowing off everything your telling him to do - figuring , he knows better

If he's truly done everything and it's hooked up right - you shouldn't be having anymore problems like that..

Hopefully he won't take advantage of you - that could get costly if he doesn't know what he's doing - I would take it to the dealership at this point if you can't work on it..

I'm not familiar with ford engines, but all the work is being paid by used car dealership. I've been reading the Haynes Manual on Fords, but why pay anything out of my pocket? Waiting to hear from the dealership now and will demand that they take it to ford at their cost. Or, just hire you
