Mitsubishi Repair: 02 lancer, idleing issues, free god, autozone

Question
Hey I have an 02 OZ rally, just recently when i start it up the car will run normally, but after it's warmed up and driven for a little bit, the car will pulse, as in instead of staying at the normal sharpness it will sit at 1500 and pulse to 2200 Rpm non stop, just up and down up and down, and then it will spike up to sharpness all the sudden stay there for 2-3 seconds and come back down and sit at 1500, until I go again, and stop at another stop sign or push the clutch in. Any ideas as to what could possibly be wrong??

Answer
Josh: It could be a lot of different things, but I would start out with having the computer coded. As the computer controls everything in your car with the help of a lot of sensors through out the car. So by having the computer coded it would show if any of the sensors are getting weak or there is a problem with the computer. If you have an AutoZone close by they will code your car for free.
