one thing is asking u guys about cleaning it but what's kind of cleaning spray from Throttle body Cleaner or Carb cleaner spray?? tell me how u do that to cleaning the EGR or DPFE?
Two posts below this I have a link you can click on for the TB cleaning. Use TB cleaner, not carb cleaner. You might even consider getting some Berrymans B-12 chemtool and an old toothbrush to make it all shine - good stuff.
