2015 outlander sport has been experiencing loss of power and then suddenly stalling and low idle and now ASC light and rpm increase/surge everytime in gear!! With the ASC light on the car won’t even move….

the car has had a bad down stream 02 for awhile

threw codes for MAF/MAP and IAT when it started stalling and losing power so I replaced the MAF first since the MAF also contains the IAT on this car, got a new air filter and pcv valve, cleaned the throttle intake and now the car idles and Revs good IN PARK when I put the car in drive it will idle fine for a few seconds then kick and begin to rev like a lawn mower surging from 1000 rpm to 1500rpm while throwing a ASC service light, rattling the cabin and throwing a torque converter code when it’s happening turn it off and immediately turn it back on and if it doesn’t return to that lawnmower condition it will run very poorly dropping rpm’s as low as 200 before kickin back up to 700 and if I turn it off AGAIN and come back a few mins later it will be back to idling and revving fine in park.

doesn’t really surge rpm when the car is orientaed more flat in the driveway, will just increase rpm by 300-400

it’s like a massive air leak but the car is fine until in gear????

what the hell is going on????
