I have a 2011 with the following mods, VMP 2.59 pulley, Innovators balancer, Kooks LT's, Kooks catted mid pipe, Magnaflow Competition catback, LCA's, Ford Racing TB, Cobra Jet intake, AFCO dual fan H/E, and probably other stuff I am forgetting.
It randomly stutters with a varying degree of severity. Sometimes the maintenance needed light comes on and restarting it usually solves that specific problem. Sometimes the stutter also goes away on a restart. It doesn't set off the check engine light. Sometimes it will clear up after 10-15 minutes of driving.
I've replaced the spark plugs, cleaned the maf, ran injector cleaner, and replaced the fuel filter. If you put the hammer down the problem seems to go away but there still seems to be some power loss. Also, going WOT makes the stutter worse once you lay off the throttle.
I just can't figure it out.
