EGR cripple...not delete (3 Viewers)

I used the kit from @LC4LIFE so I can keep everything in place if I need to and easily reverse.

Don’t over think it. It’s that simple.

I just ordered the kit from @LC4LIFE and am looking forward to the package arriving.

Just ordered the kit as well. The EGR and the P0401 have been a headache for some time. As Colorado tightened the emissions standards for older vehicles it's made it really tough to stay in compliance. One of the reasons the 80 is living a retired life in SC now.

The 'Test kit' plug will disable the EGR. The BB's are there to prevent the risk of a vacuum leak, just in case something around there is awry. Like @baldilocks said, if the EGR was stuck open, the idle would be all wonky. Simply disabling the EGR gets rid of the majority of the heat near the harness, the rest is likely heat soak travelling through all the metal in the area. If I remember right, although I should probably re-read the FSM, the exhaust does not get past the EGR (like the drawing in post#4) and up to the modulator unless the EGR opens. That opening is based on a variety of things, engine load, coolent temp, speed, etc. My kit stops it from opening. And yeah....don't overthink this.

So with your kit I don’t need to source an actual metal block off plate? Man I ordered your starter disconnect switch a few weeks back and wish I ordered the EGR kit at the same time. No worries though.

In this Post he said "The plug I build gives the ECU the signal it needs to avoid a CEL by simulating the temp sensor. You have to block/plug the vacuum lines in order to prevent the vacuum from opening the EGR valve. Its a pretty simple installation, but there is more info in these threads if you want to get into the minutia of it."

EDIT-- so the kit solves both problems----the bb's turn off the valve, the plug solves the ECM problem.

But it still seems like blocking the heat to the EGR would independently be a good thing.

Again, I wish some enterprising person would make a round plug that goes into the pipe/EGR valve connection to just block all the exhaust gases before they get to the EGR valve.
