4/6/14 I completed the dreaded installation of the new PCV (box) on the front side of the engine. Of course this involved removing the intake manifold and all the other joys that go along with this job. I purchased all items needed new intakeand ETM gaskets, new "box", hoses and clamps required from one of the major online Volvo parts sites. I did my research and came about a guy who has a website whom was extreemly knoweldgable and helpful, having perfromed the task I was taking on several times prior, sharing tips and how to's with me. I didn't purchase a new J-Tube for the job opting to clear obstructions and clean the internals of the stock J-Tube, as the problem I was having was due to reduced PCV = restriction in the short (4-5" inner circut/small diameter pipe) tube length from the banjo bolt to the larger tube. The problem I was at idle the rpm would lower to around 500, the engin would almost stall and then rpm would jump to 1200 and settle back to around 800 or so. This would happen when idling in gear or netural with usually a 30-45 second gap in between occurances. The "service engine soon light" would stay on for days and then disapear for days coming back eventually and repeating the disapear/reapear senario. All the time regardless of the SES light the idle surge situation was there. But "never" was there a "Check Engine" light - never.
So, I get everything torn off and cleared the J-tube small circuit tube and all the other tubes in the multi circuit J-Tube system (man that small tube was clogged big time - when I was done it and the others flowed freely). I even cleaned the (yucky) ETM, reinstalled everything with new gaskets, hoses, clamps, checked and double checked the job - I'm anal like that, I'd prefer to do the job once and correctly taking more time than really needed than quickly doing the job only to repeat later due to an "Opps, I guess I missed that". So after reconnecting the battery I was hope-full she'd fire right up and run like a top. I was rewarded with an engine that purred like a kitten holding a firm idle of 750 rpm (I think it's 750) in any gear or netural. My wife exclaimed it was like driving a new car!
Fast forward 20 days (4/26/14) I arrive home from a business trip and my wife tells me "by the way the engine light thingy is on, but the car is still running great". I'm like WTF now!!! So I go out hoping it was a service soon light but indeed it was check engine. And with the help of my little toy OBD II code reader I was able to obain and clear the code in the subject of this post. I might add the code comes back around 50 miles +/- and I can't find a darn thing - not a cracked/failed vacuum hose or anything. I did manage to snug up the intake bolts (all of them) about 1/8 - 1/4 turn and checked the ETM bolts which were fine. The car didn't pass emissions first go around - due to me clearing the code and then driving into the emission bay - apparently the car needs some time to reset/learn all the sensors - and the PA state system picked up on missing sensors yeilding a Failure! Because the PA emission system will allow a pass with one missing/unfixed code - "as long as the check engine light is not on during inspection" I was able to clear the code - drive until it came back on keeping track of miles from clear to re-appear" and get it to the inspection station with 5 miles from repeat of code so I now have stickers on the car and a bit of time to figure out what's next.
So, at preasnt I'm at a loss as to where to go / what to llok for next.
BTW: the guy with the website that is very helpful let me know the only thing he could come up with was from a post (on I think FCP's site) that this P0442 is associated with the "J-Tube" - which I "just" had out and cleaned??? Not a fun job either BTW.
Any help is appreciated.
