a couple weeks ago when I sat down in my truck I heard a 'crack' sound. I'm 5'2, 146lol so what the heck was thatlol When I started the engine, I heard a loud 'pop!' Everything seemed normal before and after that. For the past 6 days while driving, he will run fine then act like he is not getting enough fuel. The fuel pump & fuel filter were changed 5 months ago. The tank is 3/4 full; I added two bottles of fuel additive in case its water in the fuel. That has not helped. What shouold I have checked and how? Janie
