I just took the EGR off, cleaned it, replaced the gaskets and put it back on. Also cleaned out the throttle body and replaced the air filter. During a quick spin I didn't notice the usual lurching at stop signs or hesitation on take off.
But when I pulled back in, I could smell a burning smell. Popped the hood and didn't see any smoke, and the smell went away fairly quickly.
Do the new gaskets make a smell when they warm up, or would it be maybe from the intake cleaner and left over loose carbon?

 

You may have goten some oil or wd40 if you use it on the exhaust.
