Question about 2006 Ford Expedition
First, please have it towed to a different shop.
The mechanic you have now should have fixed the second problem under his original guarantee. I doubt he has the skills to diagnose the problem correctly.
Keep in mind I am getting one side of the story without the details. But anytime you have work done and it is not right, never pay for more work on top of the original. At least without a second opinion.
If you want to discuss specific problems I can advise if given the details, such as trouble codes and the components replaced.

Have the following tests performed : fuel system pressure test cylinder balance test as well as a injector balance test. Preferable an ASE Certified Tech will do the testing.Depending on what he/she says wel'll take it from there. Gotta know why its misfiring before we do anything else. Cat and 02 sensor respond to engine's combustion process
exhaust product.Lets see what the testing says.
Keep me posted

Do a compresion check, if Ok then timing chain is ok, try some throtle body cleaner trough a vac. hose while cranking if stars, fuel pump is out, another way if you have no codes the most poss. cuase is your fuel pump, check press is gauge handy

. The answer is to replace all the spark plugs and wires. Even if the plug appears fine to the ***** eye, and the wire has no visible damage, there could be problems with it that cause it not to fire properly. if you have coils on it, check them also.
An ignition coil that is failing will still provide current to the plugs, but it might not be enough for a full spark and the car will run sluggishly. If the current being provided by the coil isn't consistent, the car will run rough. make sure your getting good spark from coil first. good-day !
