My check engine Light came on the other day and i went Auto Zone for the Trouble Codes: P0308 #8 cylinder misfire detected, P0316 Crank Sensor Condition, P0358 Ignition Coil Primary Circuit Condition #8, P0128 Coolant temp is always Low. I pulled the coil on #8 cylinder to find engine coolant inside. Can anyone please offer some advice as to what may be the problem? The truck was always running good up until this point. I checked some other forums and they say that the intake manifold was made with some plastic which could crack over time and leak into coil. From what I can tell this manifold problem was replaced back in 2002. Can anybody confirm this? Apparently the job is quite expensive. Any information would be most appreciated. Kevin
