then took it to another place and they told me it could be the air mass sensor

Sure and it could be the kanooten valve !

... and that there is no way that 3 spark plugs and 3 coils would go at the same time.

Well it is not likely.

I have been looking at the engine and I think I can replace the plugs myself by removing the manifold first just to see if that does it.
thanks for any feedback !!

You
DON'T want to remove the intake. Much more work than you think get it re-installed. The plugs can be removed without removing the intake.
Before you do anything you need to check for vacuum leaks. These will certailyn make the engine run rough and can run you around in circles with odd Diagnostic Trouble Codes (DTC).
If you don't have the tools/expertise take it another shop and just have them change your plugs, your due. I can't imagine them charging more than $200 for all 6.
Then, take it to a large auto parts store. Most of them will pull the DTCs for free. As a matter of fact, after the new spark plugs (and
when was the last time you replaced the fuel and air filters ?) disconnect the battery for a few hours (which will clear all codes) and then drive the car for a day before pulling the codes.
