After doing the replacement/modified harness job about 2 yrs ago, Ive sinced noticed that there is some oil at the Egr Modulaor plug, when I cleaned this plug, I noticed the car excelerates nicely and doesnt make it difficult to change gears due to the engine holding higher revs.
My question is does the EGr plug need to be plugged in if you've done the EGR Mod??

cheers
