Rough Idle in a 97 sport

[XXXplorer_nc]

About 2 weeks ago my X started idling rough so I took it to my "trusty reliable ford dealer" (yeah right lol). Anyway they did there mojo to it and came up with nothing as far as computer codes, but they went ahead and reset the computer and cleaned out air reg valve (I think is what it is?). I have it plan to get a new O2 sensor (how does everyone like bosch O2's?), It has bosch platnums plugs and wires that are only about 20k old, K&N filter thats only about a month old (bored box) and I guess i'll go ahead and replace the EGR valve while i'm in there. So heres the question....What am i forgetting? Thanks in advance!!!

could also be IAC, common problem, had to replace mine at about 50k

IAC??? Not sure about that one....what is it in english LOL I'm pretty sure that the MAF is what ford cleaned out but I'll make sure to check it anyway just in case.

Idle Air Control Valve, sits onton of the engine and does what it says, your engine will run rough when it is going bad.

Simple stuff first, clean maf, replace tps, replace /clean iac.

Then you will need to break out the hard stuff it that doesn't fix it : vacuum gauge, voltmeter, and fuel pressure gauge.
