Subject: Re: 96 Engine Miss by toptechx6 on 2011/8/10 9:37:53 For future reference your 96 is OBDII and is therefore required to have misfire detection, that is what the crankshaft position sensor is used for. The PCM continually monitors for misfire on each cylinder, but will only set a code or illuminate the MIL when misfire exceeds a certain threshold or percentage of total firing cycles. Misfire counts can be observed for each cylinder on a scan tool even though a code has not been set, this can be very helpful in situations such as you describe to identify which cylinder has the problem. Next time you have a scan tool connected to any OBD II vehicle page through the parameters available (PID's) and you will find the misfire list for all cylinders. To prove to yourself that it works, unplug one of the injectors while watching the misfire monitor and you will see misfire counts on the cylinder with the disconnected injector start to climb. If you leave it unplugged long enough eventually it will set a code and illuminate the MIL. |
