Has anyone else had their butterfly valve for the EGR malfunction?

 

Not sure if you confirmed a failure, but when my truck was new, I had a K&N air filter briefly installed. The oil contaminated the Air Meter, and it threw some codes. The dealer briefly chased the EGR valve as the source of the codes before realizing I had a K&N. He cleaned the meter, canned the K&N and I was on my way. I’m sorry I don’t know the specific codes, but thought I’d through that out there.

 

Yeah I wasn't getting any codes because I'm deleted and tuned which disables all that. With the butterfly valve unplugged it appears to be running fine. It should have been unplugged anyway since the EGR is blocked off.

 

was it a 0273 number? Thats what I keep on getting.... yes i have a K&N. The thing is that I only get these codes when its cold out. During the summer i don't get these codes.
