Okay, so you changed the spark plugs, check the face of the plugs and see what they look like. They should not be black with soot. Also change the wires since it is possible that they are cracked. If no result from that, it is possible that the Camshaft position sensor is not working right, as well as the Crankshaft position sensor. Clean the Idle air control valve, or replace it if necessary. The only other thing I can think of right now would be to clean the Mass air flow meter and definitely check the coils.

I forgot to mention that a mechanic told us to check the catalytic converter. So my husband took the exhaust loose from the manifold, and it still runs like crap. Any ideas?

Did it run okay before the oil change?

Not really. The idle was off a little, it has a vibration when idling or in gear, and other minor issues.

He has now taken the EGR valve off (which is black inside), and the inside of the intake is black as well.

A car needs 4 things to run: Air, fuel, spark and compression. If any one of these are missing the car won't run well or at all. My suggestion would be to check the spark plugs to make sure they are sparking. This can be done by removing the spark plug, contacting it to a metal engine component and turning the engine over briefly (Do not let it run for any extended period of time like this). Be sure to wear some nice thick gloves so you don't get shocked. Fuel should also spray out of the hole that the spark plug was in. Check all your cylinders and be sure each one is getting fuel and spark. Let us know what you find.
