I've read that people remove these solinoids but isn't the EGR system controlled by these? So wouldn't the EGR system not function properly and the engine would run crappy? Removing the EGR systems is not as easy as other pollution stuff so I'd like to keep it.
Any thoughts on this from people who have removed the TAB/TAD solinoids. Do you have a motor that runs bad?
Does anyones have pics of the TAD/TAB solinoids or where they have mounted them? I trashed mine 2.5 years ago when I stripped my donor.

Hi Puddy,

Whilst EGR and TAB/TAD are parts of the emissions stuff I don't think they are dependent upon each other.

My engine has the EGR system still installed but the TAB/TAD and the accompanying Air-Pump and plumbing are long gone. The computer "thinks" the TAB/TAD stuff is sill there by the addition of 10k resistors in place of the solenoids.

The engine runs and idles just fine.

Hope this helps
Dave

TAB and TAD are part of the thermactor (air pump) system. The EGR system is completely independent of the thermactor system.

Does anyone have pics of what these solinoids look like?

Hi Puddy,
Look here for a pic: TAB/TAD Pic

The TAB/TAD are the two solenoids on the bottom with the white caps on the tops. On the Mustang these are mounted on the back side of the strut tower on the passenger side.

Hope this helps! Rod

TAB = Thermactor air bypass
TAD = Themactor air divertor

Neither TAB or TAD is part of the EGR system.Located in the same area is the EGR regulator...This is where the other end of the vacuum line on the EGR solinoid connects to and is required for the proper EGR operation.If you are'nt going to run the TAB and the TAD cut off the connectors and solder in resistors.Do a search for further details on the resistors.

When putting in the resistors, do they go in a certain way? Is there an in and an out side to the resistor or can it be soldered in either way?

Cameldog,

They can go either way. For resistors, it doesn't matter which end is up.

Thanks for the pic, is that the EGR regulator above the TAD/TAB solinoids? Do I need this for the EGR system to function properly? thanks.

Do I need this for the EGR system to function properly?

Yes.

Hi Puddy,
Yes the thing above the TAB/TAD solenoids is the EGR vacuum regulator solenoid and you would need it for the EGR system to function.

Cheers, Rod

BTW Puddy, here is a better pic of the EVR solenoid off the car.
