P0171 after boost, need advice.

Okay, I've installed my stock airbox back, and slapped on a K&N filter. I like the car much better than the stock air filter =], even the injen. It's quieter.

Anyways, I'm still experiencing the clicking noise at idle. I think it's one of the pulleys hitting on the idler plate, because when I pull the plate towards me when I'm standing by the passenger side fender, the noise goes away, and when I push it towards the engine, it gets worse. I will try to see if I could resolve it by tightening some bolts or something.

Wow...and I was just going to post a thread on the idler pully replacements. I'm still going to, so see that thread. You might have a bad bearing in the pulley and may have to replace it. You can get them from Amazon (Dayco brand). PM me if you want P/Ns.
