Problem with 2003 Lancer ES
My gf's car has been having some issues and we can not figure out what the problem is. The car will run fine when it is first started, but once it warms up it has a very rough idle when you stop and will sometimes die. Also sometimes when you start the car it will rev higher than normal and then level out. Both the battery and the alternator have been test and both came up good. Any ideas?

if you havent had it fixed yet i'd take a look at the egr valve might be some carbon build up due to some peoples idea of dry gas/injector cleaner products that dont clean up well. if u can get ur hands on a scanner that checks all sensors its ur best bet to record the log and send it over. youll notice if tps or anything is not functioning correct. i have purchased one of these scanners and the 220$ was worth it as fixing vehicles is much easier now. elminate the whole could it be this and change 1 part not 10 
but egr is only like 2-3 8mm bolts usually easy to find on our cars too so give it a shot
