I just wanted to know if there is any special way to clean the EGR. Do i take the whole thing apart, should i replace the gasket, do i need to watch out for anything. Just stuff like that. Im askin cause i pulled a code 55 (Exahust Gas Recirculation Fault ( EGR Solenoid # 3 ) and could that code be a inter-mitten one? (i put up a thread up a week or so a go about whats its doin) just the car is runnin like crap and need to doin somin about it. would the EGR kill my gas mileage i only got 200 miles to the tank or does that should right? I also have a code 56 (Quad-Driver " B " Fault ) could these to be related? i did some searchin and found that i might need a BCS. I just want some ideas before i start throwin parts in.

thanks keith

Here'* an answer from a search on "cleaning EGR":

Does that help?

I disagree.

I have a digital EGR on my 93. I get one code or another about once a year. I spray it with a solvent (WD-40 will do) and brush the springs and shafts IN PLACE with a toothbrush.

Then I spray each spring and shaft with Rem-Lube. Code goes away every time. No reason to remove it for cleaning UNLESS the above doesn't work. If you remove it, you will need a new gasket.

had the same issue. Had a blown fuse under the glove box. 2-3 bolts to remove cover and on the right side of the passengers feet are fuses. Maybe it is blown

ill have to check that. i didnt know there were fuses over there, but thank you

Doesn't hurt to check, but I can tell you from experience that the fuses are not a likely (but are possible) cause.

Carbon buildup on the valve shafts is the most common failure by far.

i sprayed the EGR and lubed it so far code 55 is gone but im still gettin code 56 quad driver B fault. I know that it controls the EGR , TCC, and Evap purge. Im pretty sure my TCC is kickin in and i sprayed the EVAP and didnt get any stumble. But im still not sure about the EGR. Any ideas?
i was just lookin at prices for a EGR valve and i found 2 at advanced auto parts one was for 220$ the other for for 305$ and then i found one at auto zone for 62$. so my question is why is there a huge price gap and is there any brand i should stay away form on these.
Sorry Willwren i didnt think to add to ones of these.

im startin to think i need a new PCM cause my car is shifting hard and after i put the map sensor in my boost gauge was fine and actin the way it should and now it back to +5 or 6 PSI with the key forward but not started. and my code 56 just want go away i dont have any vacuum leakes, my Tcc is engaging and my evap purge seems to be workin. Im just not sure what else it could be other then a bad PCM.
Sorry for posting so much on this i just have no ideas left on what to do.

I get the impression that your EGR is no longer a problem and that it is not that common to have to replace them. Just clean and lube them per Bill Wren'* post above.
