My intake doesn't have EGR runners.
I have no emissions equipment.
The EGR will not add exhaust gas to the mix.
When open, the computer should think it's adding exhaust gas.
That should alter the timing/mixture incorrectly.
I need to disable this.

Do I need a resistor for the EGR plug, or will that continue to trick the computer and cause poor timing/mixture?

If I just disconnect the vacuum lines going to all of the emissions equipment (TAB/TAD/vacuum tree on pass side), will that fix it?

I want to measure mine. It doesn't look that tall.

The resistor will fool the ecu into thinking that it sees egr voltage therefore eliminating the CEL. This is all fine and dandy until the ecu leans out the mix as it's supposed to do at cruise. This leads to potential pinging and predetonation. Personally I would just leave the plug open abd deal with the light or have the ecu flashed to eliminate the egr function completely.

Will disconnecting the vacuum line help the situation by letting the computer know there is no vacuum and therefore exhaust gasses going to the EGR?

Just leave the sensor unplugged

Unplug the sensor

Computer will disable the EGR function. You will have to live with CEL unless you get a tune.

From what I understand putting in the resistors puts the EGR into a state where the computer recognizes it is there, eliminating the CEL, but thinks it is faulty and thus doesn't use it in the tuning. Regardless, I'd recommend get a Moates and taking it out of the tune, it's dead simple (changing a 1 to a 0). Plus then you can do all the other fun tuning stuff that really makes a difference.

Do I need vacuum lines going to the TAB/TAD and should they be disconnected as well? I have no Air Conditioning and no smog pump.

As suggested, the best way to eliminate the EGR is with a tune. For the TAD/TAB, if you don't have the smog pump and related parts, just cap them off and tuck them away or eliminate them. You will get codes but no CEL.

I don't have the smog pump, cats, TAD/TAB or EGR on my car. I wouldn't recommend no EGR for a car up north though.

Cool, I'm hoping to improve my tune, I'm currently getting some surge and stall issues at idle. The cold didn't seem to affect the car much last year without EGR passageways with the sensor plugged in. I'm talking about -28 F actual temp, not wind chill.
