Care about the environment? In my opinion, blanking EGR is not illegal here. Our government does not measure Nox nor they are capable of knowing. The standard test at LTO is only Opacity test w/c is only particulate emission, not the invisible Nox.

Another is, EGR only works when the engine is idling(on diesels). Cruising speed and its shut like it does not exist.

Sir 12vdc...

Those were points to ponder... well taken
Also LTO's testing opacity of particulate emission, didn't know that before. I just ask testing center if readings are still low or critical.
Nonetheless, I'll see what the reading is on my fortuner which doesn't have it's EGR blocked, due for rehistro by Jan, and it's no longer warranty.
Maybe that will dictate what I will do with the new rig (montero sport).... BTW, mileage on 3 yr old fortuner is only 21k

So is it safe to say that ordinary stop lights idling is alright?... I am fortunate not to be driving in rush hour traffic (EDSA, C-5, and Manila area)
This way my EGR only actuates in stop lights.... very enlightening.

Thanks a lot !!
