noisy injectors

[steweyau]

Howdy

My 91 vn wagon is up for sale but.........
It is running rough and missing. At about 100 kph it shudders like something has fallen off. Once I back off it's fine (as far as shuddering goes).

There is a loud ticking/clicking noise from the right bank of injectors.

I have a couple of ideas.

1. There is no fuel and they are all clicking

2. One of them has no spark and there for not working.

If I had to guess I'd say there's no fuel getting to them but that would mean the car is running on three cylinders. If so I'm mildly surprised that I got to 100 kph. I took to electrical connection of the rear injector which made no difference at idle.

Any thoughts?????

cheers

vibration could be tyre balance mind you if you only running the left bank of you engine that is bound to upset the balance aswell. if you put i screw driver on the enjectors and you ear to the screw driver do they all sound the same, if some arnt firing you've either got an ecu problem of just faulty wiring
