before i installed my turbo everything was perfectly fine. i've been driving with the turbo for a couple months now, put about 3k miles on it since. when the weather is colder (50-60 degrees) the car starts and idles perfectly fine. when the weather goes into the 80's and 90's the car doesn't want to start. once it does, it'll idle at about 100 rpm and wants to die; i have to keep my foot on the gas to keep it running. it sounds almost like a cylinder is out. this goes on for around 30-60 seconds, after which the car will start to idle normally. from there on it'll drive and idle normally until i shut the car off. i know the car runs super rich at idle, especially at startup. the tuner said that's normal for a car tuned with crome. regardless, it does start and run ok when the air temp is cold. does anybody have any idea on what the problem could be?
