That takes time and again, I'd want to replace o-rings on injectors. If you're going to spend the hour to do that on the 3100, just replace the injector and see if it corrects the problem. Not worth ripping it apart twice.

Some people ohm test injectors, but the 3100 does not give easy access to the injector plugs without removing the upper intake (again, might as well replace it).

But I was wondering if there are other symptoms that may help confirm an injector OR point to another issue.
