Hi

Please below readings from injectors

At Idle
18:03:10 Group 013
-0.41 mg/str Inj. Quantity
0.49 mg/str Inj. Quantity
-1.00 mg/str Inj. Quantity
0.93 mg/str Inj. Quantity

At around 1300 rpm
18:05:03 Group 013
-0.85 mg/str Inj. Quantity
-0.36 mg/str Inj. Quantity
-0.79 mg/str Inj. Quantity
2.01 mg/str Inj. Quantity

Engine is quite lumpy at idle, when at 1500 rpm it shakes your teeth out!

There was a previous fault with injector 1 (short to plus) which was cleared about 4k ago, but injector 4 has been replaced about 18months ago. Does this suggest the rest are toast?!!

Thanks
