I'm pretty sure it's a fuel problem. I've changed the fuel filter and that's about it, I'm probably going to pull the injectors and look at them next. The engine bogs down and just kinda sputters when I accelerate, it will eventually work through it and then it's like there's a rocket on the back of it and takes off. And it seems to do it while climbing hills also. Would it be the injectors since it does run good after I get past it bogging down??? I thought if it was injectors it would cause it to run bad all the time? Any advice or opinions would really be appreciated. Thanks a lot
