Doesn't like to idle when warm (new motor)
 
I just installed my new motor, it fired right up and idled fine even when up to temp. Turned the car off and when I restart it I have to give it some gas to start and stay running. I am running speed density and the only things that have changed since my last motor is a forward facing turbo kit (stm) and bigger cams. The car runs and drives normal, it just wont idle without some gas. Fuel trims are less than 5% at idle. I can let the car sit for a few hours and it will fire up again (no throttle) then it will do the same thing. The coolant temp sensor is reading normal on my scanner also.
