I have a 1994 Blazer 4.3 vortec vin W. Could anyone post a pic of where the EGR Valve is located.

Anyone ever put a restrictor plate on theirs?

 

No pic, but it's on the front of the engine, on the passenger side, under the throttle body and sorta behind the AC compressor. The electrical connector is on the end facing you. It's about the size of a soda can.

You'll need a 10mm wrench (ratcheting if you have it) for one bolt and a 10mm socket with at least 9" of extensions for the other bolt.

No restrictor, I don't like screwing with the computer, but I did put the $5 Dorman/HELP! screened gasket on mine.

 

where is everyone getting these screens at?

 

In your local autoparts store, in the HELP! aisle. Hanging on a hook with the various HELP! parts, like replacement lighters, window handles, etc.

 

autozone has the screens there made by tomco
