Hi all - new plugs and leads on my D2 V8 and still has a stumble at idle on petrol only - does not do it on LPG, so its reasonable clear that it was fuel side not electrical.
Had the injectors out and tested and the spray pattern at idle was crap - big drops (relatively). Mid to high revs the pattern was good - and that makes sense given the crap idle response and good mid to high range acceleration. Ultrasonic cleaning made the spray pattern at idle very good again. The injectors are going back in tomorrow so I will report back. The truck has only done 65,000 miles, so its a bugger. They reckon its crap fuel thats done it.
Cheers
