My 5.7 hemi swap has me puzzled. The engine doesn't smoke at all on startup,but once it comes up to temp, it starts smoking out the left bank. I never saw this engine run before the swap. I replaced the heads and one piston/rings due to two dropped valve seats. The cylinder walls in all cylinders looked great with some factory crosshatch still visible. I also have a miss, but how do you find it in a computer controlled engine? Will a scan tool tell me witch cylinder is not firing? I don't have much experience trouble shooting computer controls. Help.
