The guy put the cheapest plugs in right out of the box. the vehicle is getting only 14-15 mpg and has a minor skip. I found a vacuum line discounted by the right fender, the vacuum size line is a part of lines going to a small clear filter that looks like an inline gas filter. These line have a few straight and T fittings and numeous hoses going everywhere, two down under, one behaind the radiator, one to what looks like a canister filter with larger hoses connected to it. I believe it's all part of the evap system. Is this filter just a simple gas type filter or (let me guess) one that should have silca moist asborbing crystals of something. Napa didn't list one. Is that filter a maintennance wearout item and exclusively a volvo part ? Please inform if you know.

The lines you describe are the window washer lines and filter. The disconected line is and overfill drain for the pump.

Yes, check all of your small vacuum hoses for leaks...sometimes these hoses will expand when hot and open up, allowing unmetered air into the mix. When cold the leaks are not as noticeable. There should be a vacuum hose diagram under your hood, so look for that. Otherwise, there might also be a small leak or hole in your turbo hose(s). Check for those. It's nice to have Romanian members here! Good luck and let us know how things are working out.

Yes, it is one of those silica filled filters- often called the charcoal filter or Evap Cannister or Filter. Typically these don't go bad- but the lines to and from them can get old and cracked causing Evap codes that don't go away unless attacked and replaced at the source. Give it a good look, especially the small hoses that connect to it.
