Hello

i am curious about doing the egr restrictor plate mod to my 93 f 150, i have used the search feature on here but didn't find much with a working picture. Besides i always get side tracked reading old posts anyway, so i thought if anybody had some old pictures and a write up that would be great

any body done this in a while? any side effects.

Pictures would be awesome if there are any.


if there is a thread on this, is it possible to make it a sticky or something that could be added to this forum so it could easily be found cause from what i have read it works.

thanks for any info

 

No pictures, but try this !!

Even easier than the EGR restrictor plate would be (from an earlier post).....

"Go a hardware store and get a couple of 3/4" diameter fender washers, one with a 5/32" hole in it, and the other with a 7/32" hole in it.
Loosen the tube nut on the EGR valve and slide it back a little and insert the fender washer with the 7/32" hole in between the EGR valve and the flange for the EGR tube then snug it all back up.
This will allow EGR to flow (at a reduced rate) into the system and keep the CEL light off.
Test drive your truck a couple of days. If there's the slightest hint of a stumble or hesitation, do the above again and replace the washer with the 7/32" hole in it with the other washer that has the 5/32" hole in it.

In a sense.....it's an inline EGR Restrictor Plate !!!!

My total cost for this fix was 34 cents....and that was for 2 washers !!!! "

Much easier to install---1 nut*** EGR Tube Nut *** to loosen/tighten
Already fabricated
Hidden from the smog *****' visual inspection


That should get you going !!

thanks for the reply i will see what i can get up to with this on the weekend

 

Thanks for the post. The 3/4" fender washer with a 1/8" hole fits nicely between the pipe and the EGR valve. The washer edge was ground down a bit with a dremel tool to make it fit nicely.

End result: eliminated the excess EGR flow and all the off-idle bogging the truck has always had is gone. Gas mileage is up, and so is the off-idle, in-town, and highway speed performance. There is no spark knock or change in coolant temp after the mod. No MILs either before or after the mod.

I live in SE New Mexico at a low 3300' altitude. YMMV.
