S80 t6 idling problem and tps/throttlebody

[nskhellfire]

Hello my car has been running perfect but I decided to check things out I took out my Tps or throttle position sensor in hopes to clean it and have a better running vehicle and it was a little dirty however the gasket was bad... Once i put it back on I saw that the car idled really weird and was louder it idles at 1100rpm and fluctuates... I heard there was a recall on the tps and I wanted to know if this was true because i called the volvo dealer and they kinda pushed me off the phone saying "there is no recalls on that vehicle sir bye" No idea why they were rude to be but however I had taken my intercooler tubes apart and saw that the steel braided hose that comes straight into an electrical thing that plugs into the intercooler tube that says "Twin Charged" Well that steel hose was covered in oil and when i took that intercooler tube off it leaked about a quarter size puddle of oil is this normal? Also i dont think i had a pcv clean and im not to sure where the pcv is... I guess its right under the tube that comes off the MAF Sensor hose which that tube also has a vaccum line connecting to it. Correct me if im wrong there but that hose is very stiff and seems dryrotted is this normal and my car has 101,000miles and i am pretty sure it hasnt had a pcv clean... What do you suggest.. I was first scared my turbo was going because I saw oil in my tubes but I saw no oil in the main first tube on both turbos so i am guessing it is from that steel braided line i mentioned earlier... Also is there a recall on this tps??? If so i dont have to buy the gasket and I could just get it replaced. I heard something about having a white sticker means original and yellow means replaced mine has neither and has never been replaced and has that weird black thing that says volvo on it... iM guessing that would be the sensor considering its electric thank you for the support
