'84 Base model EGR?

Postby Panamerica » Sat Sep 16, 2017 11:12 am

Okay, so my 1984 Base model was taking too long to maintain an idle and then stalling on takeoff. So I run my OBD I reader and get an 83 and 84 which point to the EGR Valve and EGR Valve position sensor which I just happen to have handy.... Sure enough the old valve is a blackened crusty mess... I replace both parts (its surprisingly easy) and things get MUCH better but the problem is still there-Not as bad but still there.
Also, I'm still getting an 83 and 84 on my reader... any suggestions? I don't notice any air leaks...

Thanks!

PanAmerica, You have fixed the problem. Bravo! Now disconnect the battery for 10 minutes and then reconnect it. This will erase any stored codes. Of course you will have to reset the clock and radio afterwards and the computer will have to relearn idle speed, but thats no big deal. Just turn the wheel lock to lock with all lights and accessories running, then shut off the engine and restart. Drive the car around for 10 or 15 minutes. If you get any codes after this then the computer is still detecting a problem. Good luck and let us know what happens.

Thank ~you~ for keeping a Lincoln Mark VII on the road.

I did some digging and found these pictures from 2005 and my (late) 1984 Base Model.

Wow... Looks like I've got a bit more cleaning ahead of me... All I did was clean the EGR valve... Sheesh!
