Was wondering if you checked your fuel flow. I was having similar problem a few weeks ago with not wanting to mph. I usually take the li ne off after the regulator and see how long it takes to fill a 1 gallon jug. My issue ended up being the rotor in the fuel pump being stripped and not catching all the time.
Have a Magnaflow 500 with the filter.Rebuilt a year ago,but will have a look at the filter.
HEMI-ITIS has no cure. My condition is fully BLOWN!!
