EGR Valve,

You can remove and clean it. But I always replace them just to be sure it is in proper working order.

Waht is the proper procedure to remove and replace the valve?

Not sure about yours but most of the time it's just a couple of bolts. Usually pretty simple.

That's a good one judge. Gderrick judge needs best answer for that one. Good job judge.

Yes it happens that way some times.

Tacoma EGR----every other creature 'cept this one on u-tube, there was an Indian guy expaining the EGR, it made me laugh....guess you'd have to had a lifetime of exposure to these panupabatada types to get all lit up.~

You don't repair you can only replace
