S70 sputtering, now won't accelerate over 20 mi per hr

[tfly503]

I honestly don't know what I would do without Matthew's or the help that's available through YouTube and our online Volvo community. It's tremendous. Yesterday while driving home through my neighborhood my 850 N/A began sputtering and wouldn't go above 20 mph! I BARELY made it home and I really don't like pushing my 19 year old "Vo" when it's running like that. I made it however. I have a Volvo mechanic that I've become buddies with and he'll make house calls and he's great but his help isn't free. I looked up the problem on Matthew's and there it is! It was a loose air intake which essentially connects to the intake manifold, the idle air control and the vacuum tree. About a month ago I replaced my PCV and I guess when assembling everything back together I didn't tighten down the intake hose clamp back together sufficiently.
I'm no auto mechanic but if it weren't for the help out there online my perfectly good running, PAID FOR, 850 would probably be sadly rusting in a junk yard by now. Thanks for all the help!
