has slightly rough idle but no misfire counts b1&2 lt trims at 3-5% on road test I accelerated to 45 mph & then jumped off accelerator. scan tool started showing misfire counts on #3 up to 245 misses & set a pending p0303 but engine did not feel rough. engine was recently rebuilt as the owner got it so hot the valve seats came loose & a couple of them broke, leaving loose metal in intake manifold (new manifold installed at build)
