Known issues on Chevrolet
On GM 5.3L V8, cylinder 2 is a non-AFM cylinder, so P0302 usually points to a coil or plug rather than a lifter issue. On 3.4L V6 Equinox, intake manifold gasket failure between cylinders 2 and 3 is a common misfire cause—check coolant level and look for a sweet smell at idle.
