cxn613 Posted December 14, 2010 Share Posted December 14, 2010 Replaced egr cooler and mass air flow tube. Truck started fine, once I road tested it, it seemed kinda sluggish and 4-5 code appeared. When giving it throttle while driving it seems to have a loud air sucking affect, or maybe even a more of a whistle out of the turbo than normal. Would installing the new cooler and mass air tube cause any of this? thank you Quote Link to comment Share on other sites More sharing options...
greendog32 Posted December 15, 2010 Share Posted December 15, 2010 sounds like a loose clamp somewhere Quote Link to comment Share on other sites More sharing options...
rhasler Posted December 15, 2010 Share Posted December 15, 2010 You might check the small stainless steel line running between the valve covers to the turbo for damage, it supplies air to the turbo actuator. The VTG control valve on the left side of the engine controls air flow through the line and should provide a minimum of 95 psi. Quote "Mebbe I'm too ugly and stupid to give up!"

I don't know if its possible I bumped something on the left side while installing the new "plug in box" Quote Link to comment Share on other sites More sharing options...
