Bent Runner
 

My Driverside Rear TPI runner is almost all the way dented in. I was just wondering if that is causing 1 cylinder only to run way to rich. I experience sort of a "bog" up top, but the car still has great loew end torque.

The left rear runner serves the #8 cylinder. Since the O² sensor is located in the exhaust on the left cylinder bank, mixture problems on the right bank won't affect overall mixture control. If #1 is rich, look into the injector for that cylinder.

The "bog" at higher RPM could be related to poor air flow at #8, however. Have a photo of the damage?

yeah ill go take one
