so anyway.. when the check engine lghts on.. get get a good ride. i clear it, and i go in to a limp mode.. i got the code 3 days b4 i installed a new DV. thats when i felt the limp mode.. it was a new feeling. I just changed the PCV hoses... all of 280 bucks at the dealer in parts.. putem on. etc. that was the only hose issue i found. all the vac lines look good. i got an o2 sensor coming in, i dont think its that though, just says im running lean. maybe MAF, but i clean it regularly. (and it reas in 2.0 to 4.5 at idle.
