Check your programming in your computer. Turbo cars, especially if they are running heavy injectors, have a hard time idling if they are getting to much fuel. Most people fail to realise at igle the stock setting is too much on upgraded injectors and it needs to be turned down. You might be flooding it.

 

ecu is now low programming for rc injectores..
