I have hot start issues, but I'm not convinced it's just the injectors. When it's hot, I'll turn the motor over, and it will crank fast for a few seconds, then it will crank real slow, almost like I have a weak battery, then it will fire up fine after a few seconds. I think if it was the injectors, it would crank at the same speed all the time. I know longtube guys have problems with their starter being heat soaked. Is this possible with shorty headers?
