Burnt nozzles are due to incorrect injector settings. Being made in China does not help either.It makes sense then, why the needle on one was so burned at the tip
Good they're out I guess.
Thanks Seatman!
Had one in the shop doing something similar: IQ was bouncing between 2.0 & 0 & running like ass. Hammered it up to 4, bouncing between 4 & 2.0 then, much smoother idle & better power, but then set a hard fault for the Quantity Adjuster. Makes sense. When I started it had an intermittent fault for it. Cust. wasn't too happy about still having a CEL & occasional glow plug blink until he drove it & remarked that it had never run so well.Now I got to play with the IQ. I only get it as high as 2.2. If I try to lower it, it goes to 0.1...and idles like a harley So, hammer mod, here I come!

Looking for a good used QA for an ALH still if anyone has one for sale/trade.
Thanks DBW. I am working on buying a second set of injector bodies and they'll make their way to you for proper installation. I am still debating on what nozzles to use. PP764's or Race 520's. Decisions, decisions
R520 all the way. Mine were set up by DBW at stg1 and they put out a bit more fuel than my .216's did. And seem to have a bit better (less) fuel consumption when im not being heavy footed.Go big or go home
yep, do check it warm, but I thought that was because IQ increases as fuel temp climbs. Haven't seen a correlation between fuel temp & bounciness. Time to tinker this long weekend i guessCould be that they are checking IQ on a cold engine. The engine is ssupposed to be warm. If it is a cold engine i think you get precisely that, bouncing IQ. I may be mistaken on that, but i do know IQ is to be checked with a warm engine
