I got the code p0139 with an AEM intake, buddy club rh and LSD kitty backer. I understand the code means 'slow response'. I searched and found one mention of checking the MAF. My intake was sworn by AEM not to work well with any other year but 06, I have an 08. My dyno proved the intake made power, up to 12 whp and 6 hp over max. I do have 'lumpy' problems wit this intake. Like if its got lets say 3 lines of coolant temp when im jsut heading to work and i go past half throttle any where under 3500 rpm, my face is in the steering wheel with what feels like detonation. With the stock intake its as clear as a whistle, i can mash anywhere with no problems. i had the whole setup on and never had a code till 6k miles or so, then i cleared it and got the same code another 1k later.

So im just wondering if it is the intake.
