Lincoln Town Car EGR code 401 repair

This video is also posted on the lincolnsonline.com website. I clean the EGR channel on a 1995 Town Car.
To update the video the light came back on. I suspect I did not clean the channel good enough leading up to the intake. I will have to do it again. Unless someone has another suggestion. This should give you an idea of how to undertake the job

Well I should say this is an almost repair video because the light came back on. I suspect I did not clean the channel well enough. I got up enough courage to undertake this job after talking with a few guys on the forum. It should give you an idea of how to undertake the job.
Perhaps someone can explain the clogged port along the side of the intake device. You will see in the video. I guess I will have to undertake this job again and clean the tunnel leading up to the intake. That is the only thing I can think of that may be causing the light to come back on. I connected a big syringe with a hose attached to it and drew vacuum on the EGR diaphragm when the engine was idling I figured this would stall the engine but it did not even change the idle at all that is what is making me suspect I need to clean the tunnel better. Let me know what you think.

Had the exact same issue with my 95, I also had to change the dpfe sensor, it is bolted onto the back of the throttle body.

Like you video, thanks

@Upnorth9 Thank you for that comment about being in the same situation as I am right now. I would rather try to replace that sensor than to take all this apart again and try to clean tract again.

@queentk1 What's the actual code you're getting? blocked EGR will cause the car to run rough, hesitate, stall and will normally give you a CEL when decelerating. It shouldn't cause problems with shifting.

What kind of problems was you having with you lincoln? I have a 95 lincoln and it is having problems shifting. I frist was told that the catalytic converter's was clogged. So now that i got them fixed they are now telling me its the EGR is clogged.
