Lost my turbo!!!!!! Please help 850 1994

My 850 turbo 130,000 miles has lost its turbo. When I accelerate my wagon acts like a regular car now, it will accelerate but there is no turbo boost to it. The turbo gauge backs this up, it stays to the left of turbo area. I am also getting a shakey idle at start up. It used to rev high for a short bit then come back down to normal. Now, it has a tough time staying high enough and has even stalled once (first time for this ever). No current check engine light. I did recently replace the air filter, is it possible I knocked something loose? Don't figure thats it but you never know. Thanks in advance.

Also check the connection to the MAF at the air box.

Check all of your vacuum lines, especially the ones right there on the side of the air box. Could be you just knocked off a line that controls the turbo. If you JUST replaced the air filter and now the turbo is dead I would have to say that you knocked a line loose. I've found over the past 20 years that although coincidences doing occur in my business they are so few and far between to be classified with things like hens' teeth and rockin' horse poop.

another common problem is if you removed the hose from the idle motor to work on it and forgot to put a clamp on it it will blow off the first time you boost.
