P1041 is a problem with #1 injector or #1 injector harness. If you have a noid light, it may assist. There is also a reference to the ECM but that isn't very likely.

If it were me, I'd unplug #1 injector while running and see if I notice a difference. If there is no difference you know where to start...

As far as the ETS goes, have someone with a vida/dice run it through the Throttle body test to make sure it is fully within spec. and then clear the code. I was unable to remove that code with a regular "consumer" code reader. Some may be able, but the two I had were unable. My code was triggered by pulling the wrong fuse while running...

When you do this test it takes the reference of both potentiometers and compares them to their "theoretical" reference point of where the throttle should be at that point in time while slowly going from full open to full closed, rinse and repeat. I believe it allows something like +/- 10% but I haven't looked at that in a while. It gives a nice graph of both readings, the position, and the unwanted deviation.
