Pics from addressing CEL code 0401

[gooserex]

Clogged big time, 221K on the odo and the the passages where completely blocked. I also took the opportunity to clean the TB and file down the tbv plate screws near flush.

Clogged EGR passages...


Back side of the TB (before)


And after (not exactly perfect, but hey)


There was also the address treat of finding out that the linkage between the rear and front secondaries was disconnected, lord only knows how long it's been that way!



The car idled +500 rpm after the work was completed so she's obviously breathing a lot better now, after resetting the computer everything is nice and crisp feeling now.

The linkage hasn't been addressed yet, I highly doubt I can get the plastic fitting that holds the linkage in place so I'm going to fashion my own out of a plastic grommet and use a c-clip to hold it in place.

That looks familiar. I'm betting you would know if the linkage was broken for long. It certainly was noticeable on my 95 at the time. Also I'm sure it would have helped contribute to the clogging. Nice job cleaning her up looks great. Also maybe check the Canadian tire "help" section in automotives to find a new gromet. I'm sure you can find something somewhere. If not a quick trip to the wrecking yard may suffice.

This thread is making me want to go and clean mine as well...

Well the TB gasket it only $7 from Part Source (special order, only takes half a day) and time needed was about 2-3 hours take your time. Although I'm not sure if it addressed the issue or not since my CEL went back on again last night, gonna pull the code to see if it's back or if it's something else now.

If the front linkage is still unattached then I'd wager that this is your cel.

Any Ford dealership will sell you that grommet; it costs about 5 bucks, which seems excessive, but whatever.

Well that's good news, I couldn't find anything at any of the auto stores around here that looked like it would work.

Oh and Murphy's Law, I misplaced my code reader and can't find it for the life of me, so I have no clue what the code is now.

Again non opening butterflies on the intake will throw a code. Repair this pronto reset the computer and see if you throw another code.

Well I finally found my code reader last night and had a chance to pull the code from the SVT, it turns out it was still posting an 0401 code but that was it. Meh, looks like I'll have to start doing some hunting along the EGR route to see what is still causing the issue...

At the risk of sounding like a broken record or maybe I just missed that you did this but have you repaired the linkage yet? If not then fix it reset and then pull your code if it shows up again.
