    I have a 97 yukon 5.7 ltr. Cold starts are no problem but once the engine is warmed up it has trouble. The only way to get it to start is to depress the accelerator and hold it untill it starts. Kind of like its flooded. I have checked trouble codes and got two. 118 - engine coolant temp circuit high input. and 125 - closed loop fuel insufficient coolant temp. Any ideas on what might be causing this.
    Thanks John
