LMM: Lmm injectors

[20dmax08]

Was curious as to how you check the return rates on lmm injectors. I’ve noticed mine starting to get harder to start. When I did my heads and had them tested the shop said one had a high return. The balance rates are all within spec think worst is 1.5. Fuel rail pressure and demand fuel rail pressure always match or are within .1 of each other. Using edge insight cts2 to monitor. Injectors have about 228k miles on them. Thanks.

You have to pull the return lines and measure the fuel coming out of each injector. Typically the bad one(s) will be obvious with a much higher return then the rest
