Well.

U have 2 ways, depending on what is easiest, 3 technically.

First ohm the injectors, theyshould all be within a ohm or so of each other.

If the miss is solid and not intermittent:

Then u can pull injector leads one at a time

Or u can pull plug leads one at a time.

Obvioulsy if u have a dead cylinder, when u pull that one you should get no change and it should get worse if you remove the fuel/spark from an otherwise good cylinder

edit: If u find something suspect or have quick pressure drop even with the return line blocked, pull the fuel rail up and pressurize the system, any leaks/drips shoudl be evident then

later
Jeremy
