Most often, dirty or faulty 02 sensors will throw off the idle. The 02 sensors and camshaft position sensor basically control all the idle. If TPS was dirty or bad, you would have some hesitation when giving some gas. Bad plug would cause lack of power or misfire.

on the sohc engine there is a rubber elbow on back of the valve cover going over to a line at the fuel injection that cracks at about 100K miles and lets the engine **** air and it will idle horrible til you fix it. Check this and see if it's not your problem...I've had it happen to 3 sohc engines and the dealer wanted $400 to fix the first one for my friend...Took about 30 seconds to pop the hood and pull it off, 3 minutes to glue it back together, an hour to dry, and 30 seconds to reinstall it...
