I recently had to replace an injector, and today I dumped more diesel into my crankcase. I pulled the valve cover and performed an impromptu shutdown test by disconnecting each injector. When 1,2,3,4,6 were disconnected, there was a slight miss. When 5 was disconnected there was a more pronounced miss. The Truck runs fine when all are connected. How can I determine which injector is cracked?

I only had 5 injector circut codes. Injector 5 did not throw a code when disconnected. What might cause this?

I am also in dire need of the instructions to pull injectors. If someone could e-mail me a set, I would be very thankful. I am not a member of TDR.
