Hello, since last week my ST has ran like CR@P!! on stat-up and when idling it shakes intermittently. When I start to accelerate it really shake and if i accelerate for a long period (going up a long hill) the truck makes a popping sound (maybe backfiring?) and loses acceleration when it happens. When I am at 45-55mph i dont notice the shaking. I am getting a check engine light and when I run the scan i get 2 codes. P0316 - Missfire detected 1st 1000 revs, and P0306 - Cylinder 6 missfire detected. is this a spark plug or coil issue? or is it something else?
:cry:
