Q: Keep getting multiple misfire codes, normally different cylinders except on cylinder (0307), can this one be throwing off the rest

This may be a problem with the exhaust catalyst partly clogged causing excessive back pressure. There is a test where the O2 sensor is removed and the back pressure tester is put in the hole to see if the catalyst is clogged.

计算机应扫描查看您是否正在从不良的O2传感器中运行或出于某些其他原因。线圈也可能很弱，并且不会弹出足够的火花能量。由于该卡车发动机可能有机械师检查系统exhaust problems, engine carbon build up, cracked valve seats, O2 sensor problems, coil problems, camshaft and distributor cam gear worn problems. The list goes on and will require a qualified mechanic time to diagnose this complaint for you. If a shop or mechanic cannot figure it out then it may take a factory trained mechanic to be able to diagnose the problem down to one of the listed issues. The best thing to recommend is to replace all the tune up items first so these can be eliminated. This meanscoils,plugs, wires,fuel filter和空气过滤器， 和PCV valve.
