When were the spark plugs and wires last replaced? Could be that. Could be a MAF sensor. Could be IAC or throttle position sensor. You’d have to do more testing. The cheapest thing to try first would be cleaning the MAF sensor. Most auto parts stores sell MAF cleaner. If that doesn’t do it, I’d replace the plugs and wires (and check that the coils (or distributor) are working properly).
