I will double check the bolts, but I believe that they were on there pretty tight. I didn't disconnect the air sensor when I installed the JWT. What I mean by the a rougher idle, is that it seems to be a little less smooth, like the engine is just maintaining enough to prevent a stall. Maybe it is in my head, I will double check and get back to you guys, thanks for the input, if it is not evident I am still a :newbie: therfore I really appreciate any help.
