as well as the passages?

Just wondering cause if not, I just ruined it. I sprayed out both EGR passages as well as inside the EGR valve itself.

I did this without the truck running, and disconnected the battery.

Bout to see what happens here in a few minutes.

Carb cleaner shouldnt be a problem as long as it says that it is safe for O2 sensors on the can.

WOW :iceslolan :lol2:

BIG difference in performance! Thanks for recommending the cleaning; ran truck for 100 miles, no more CEL, throttle response is excellent.
