Nice....do you have a GAP or a different tool? Many people have referred to resetting adaptations and I know it's in the manual...but I've never done it. I'd love to hear a procedure or even a description of the experience.

I know how to do a hard reset. Are you certain that doing that resets adaptations?

As far as I know, a hard reset does not reset engine or transmission adaptations which are stored in NVRAM. Some claimed it did until someone actually pulled live data results before and after to show it did not.

Thanks for coming back with the update. Glad you got it sorted out.

As it turns out the number on the electrical stem of the injector does matter, even though they're all 2W93-AA.

In case anyone comes across this issue in the future, make sure the injectors you buy have 4280 on the electrical plug, even though other ones say they work for the LR3 with the 4.4 they do not.

Denso part # you want is 195500-4280
