My neighbor has a 2007 GT,and after a correctly installed Steeda UD pulley setup,performed by a reputable shop, he gets " Cylinder No.2 Misfire" Code.
Just wondering if any 2008-09 Bullitts have had any issues?
We swapped out the coil on plug,between different cylinders,but it soon came back.
Now we put in a new plug,and will see how that does.
Car runs strong,and no hint of any misfires,under load or idle,but it still will throw a code.
This started right after the crank pulley install.
Now, when the crank pulley is tightend up,the snout has to bottom out against something,like the timing sensor sproket, timing gear, or something,in order for you to torque it up?

Mus408. I had brenspeed install cams and pullys late Sept. Some time in Nov or Dec had # code po300 which is random misfire. Called brenspeed first thing David asked me was did they install pullys We cleared code have not had a problem since, was told to keep eye on it. If happens again they would replace them. The pullys are Steeda. JOHN

Thanks for the tip! I would like to know the connection between a UD Crank pulley and a Misfire code,just to satisfy my mechanical curiosity!
