If there's a leaky injector, you can expect things like misfiring, flat spots, lack of boost, reduced mpg etc.

........ next to godliness, don't they say???


No one has mentioned this so far, but have you checked the nut and the union to make sure they are tightened correctly?

Have you I (or anyone else) had the system apart (eg replace injectors, seals etc) due to access on this engine I've seen a few where people have replaced seals and not seated the flare correctly in the union, or even tightened the nut to the union but not the union to the injector.

For the sake of 5 mins it could save you replacing pipes, or it could cost you 5 mins for nothing, in which case ............... uh .............. sorry?

Just a word of warning too - make sure the fuel pressure has dropped before removing any pipes.

The pressures in the rail and pipes can be very high, resulting in injury if not treated properly.
