I agree.
I would change the plugs (plugs should be between $3-$6 each probably) and at least check the plug wires. The air filter should be cheap, but should probably be changed as well. And as mentioned, get it checked at AutoZone for any codes, and if any are thrown, let us know or ask the tech about them. It's very possible the sensors mentioned need changed. Depending on which ones they are, it might be pretty cheap and easy to do yourself.
