What's up guys, in need of some help with my car yet again. Recently my motor lost compression in pretty much every cylinder and the head was shot as well. Mitsubishi actually covered the shortblock and refurbished the head. I get the car back everything seems fine until I come to a stop the car will not hold idle it bogs and stalls. I brought the car back to the dealership they said there was a vacuum issue and the lines weren't on right and and one blew off blah blah but they fixed the issue they said this time. I pick the car up again mid way through my drive home car starts acting up again stalling when I come to a stop. The car has a full turboback exhaust and an ebc and an act clutch and the car is tuned by Sean Ivey at Iveytune. In need of some suggestions.

 

I'd check further for disconnected vacuum lines. Do you have any way to log your ECU?
