Neither the MAF or IAC will address a misfire. The 6 cylinder engines have a slightly rough idle to begin with but nothing you should really notice from the driver's seat. The physics of a 6 cylinder engine and the design of the camshaft make for an engine that "moves" a little if you're watching it with the hood up. "Nature of the Beast" kind of thing. You can mist the plug wires and boots with soapy water and then watch and listen for a misfire. Why did you change the MAF and IAC?

Did you disconnect the battery when you changed the sensors? If so, you have to follow the 20 minute 'training' routine to teach the computer how to run the engine properly.
