How often do you guys change your fuel filter and what are the common signs that it has gone bad? Thanks. Like many other LT1 owners, I am trying to locate the source of my low rpm stumble.

 

It's a pretty cheap item to change when troubleshooting to help rule out certain items. I change mine annually, and if I ever run into problems, I always know that the fuel filter is more than likely not the problem.

Thanks guys Hopefully this solves my problem

 

block the EGR yet ??

 

EGR is blocked off and tuned out, going to adjust the tune some more tommorow night, changing the fuel filter and coil tonight This hesitation better be gone before the dyno day on sat so I can spray

 

Great advice! I feel the same way.

 

Agreed I will never let mine go more than a year again. It is like wipers you forget how good it was for so little effort . My car has more pep again.
