XFtoXE 14 Posted April 21, 2016 Hey Guys I have a 351C xe fairmont on straight gas GRA system. My problem is, it is bogging down on acceleration and lacking in overall performance. My question is does the GRA system have a filter and if so where is it? Cheers Share this post Link to post Share on other sites
tpak addict 1,909 Posted April 21, 2016 Got pics of the setup... that may help.... May be rich or lean if its bogging down, A Dyno run may help check afr's where it bogs down... Vaccuum leaks may be another possible cause also. Share this post Link to post Share on other sites
