21 is about normal. i only get 24.5, but i drive it conservativley, shift at 2,500 rpm, and most of my driving is less than 75 mph. it all depends how how u drive, the type of conditions you drive in, and what gears you have in the rear end. get a k&n filter, header, msd ignition, run synthetic gear lube in the rear end and trans. all of that will help your mileage. go back to auto zone and get the code, and search for it on the internet. try taking the iac valve off, and cleaning it and the wire connector. then wait and see if the SES light goes off. you could always get a junkyard iac valve instead of paying for a new one. but if its a cheap part, i guess just buy the new one.
