Check the engine intake and all vacuum hoses for leaks, do this with a can of spray carb cleaner, if you hit a leak the idle speed will change. Repair what you find.

My 1997 ford expedition check engine light came on a few weeks ago when i stop at a red light the truck starts shaking real bad i think that i have a vaccum leak, and under the hood i hear air blowing

Yes if you have an engine vacuum leak it will cause this condition and turn on the Check Engine light in the dash. Please go under the hood with a can of carburetor spray and spray around the top of the engine, careful to keep it off the paint, when you hit a vacuum leak the engine idle will change, zero in on that spot. Repair as necessary.

I have a 2003 ford focus , I am having a misfiring problem. I have replaced spark plugs, wire, coil pack, air filter, fuel pressure sensor, replaced injectors 3 and 4 in which that the misfiring code....

Check for Intake Manifold leaks with either a water mist from a spray bottle or Choke cleaner. Do this while the engine is running and you will know about a leak with an RPM change. I read about some intakes were 2 piece and the intermediate gasket leaks.

Also you could clean the MAF on the air intake with Electric cleaner. If you have an old fashion Vacuum gauge you could plug in and see how steady Valves are closing by watching the Vacuum bounce from misfires.

Would like to know results on this case.

1991 Camry running rich

check for vacuum leaks especially around the intake manifold gasket. Although the engine appears to be running rich, it could also be misfiring due to being too lean in one cylinder. When the cylinder doesn't fire the charge, it goes into the exhaust completely unburned and looks like a rich running condition due to the unburned fuel. If it is a vacuum leak causing the problem, the engine will run fine at road speeds but misfire at idle and not pass smog.
