Guys my car cranks fine. It's a newly built ls motor with all new parts so I'm stumped. The idle is fine at startup then it starts idling up and down and then it bogs down like its not getting air but I can feel the intake pulling in air then when I turn it off it diesels. Anybody had this problem?

Hows the timing? Dieseling should be from overheated pistons and excess fuel. Maybe your injectors leak? Plugs too hot?
