I have a 2003 f150 xlt 4.6 liter. Seems to have a hard time starting after running a while. Doesn't seem to happen first time of use. Any ideas?

 

Probably leaking injectors. They dribble and flood the engine.

 

U don't think it needs a tune up?

 

Hard starting when warm is the typical symptom of dripping injectors. The next time you think its going to happen, push the throttle down 1/3 to 1/2 way and see if it starts faster. If so, you have your culprit.

 

I'll give it a try. Thanks
