I;ll get to the point. 03 X type 2.5 110k. A few months ago I replaced plugs and the upper "o" rings, brake booster line for P174, all good ran fine. Now she has been cold start rough (real bad). I didn't replace lower "o" rings.
I can;t find on line (parts geek ect.) the "o" rings cheap. I was told that the 3.0 parts are different. Someone said on this forum they got them (uppers) for $15.00 and lowers for the same. Can someone refresh my memory where they got them or what they used.PLEASE I paid $100.00 for the last set then some one on the forum got them for $15.00. My E-mail is billbjork@comcast.net
THANK YOU IN ADVANCE.

 

I have the same question on a 2.5, where is the "cheap" source?
