Default 2011 Lancer sportback ralliart

hey guys, i am new to this forum but after getting an oil change yesterday i have noticed my car idling very weird all of a sudden. after warming up and coming to a stop i have noticed it fluctuating from 1100 rpm down to 500 or lower. i don't know if they could have used the wrong oil, knocked a vacuum hose loose, or if this is something normal. let me know if this has already been posted and solved in a previous thread, thanks guys

This sounds like the dreaded FPR vacuum hose. Pop off the engine cover (just pull), and check to see if this vacuum line came loose...

checked the hose. everything looks good on that end. yesterday with th AC on it dropped dangerously low and almost died. with the AC off it hovers around 750 to 1000 which is normal but still drops periodically. anything else you can think that i should check?

Dont feel bad, these new cars are extremely complex, so it really does take an expert to know evrything that could possibly be going wrong.. Sometimes, Even the dealer cant find the real issue, alot of times, they just start replacing things til the problem goes away.. Hoepfully its covered..
