Well I spent some time listening to the injectors. I'm not exactly sure whether a bad injector will sound drastically different or whether the difference will be subtle. That said, I think I may have noticed a subtle difference in sound on the fifth injector. I can definitely hear the difference when the computer shuts off the fuel supply (stops clicking).

On a separate note, changing the DISA o-ring seems to have decreased the frequency that the p1351 code comes up, but it's not gone. I have also noticed that the code pops up primarily at idle. I can drive on the freeway for a long time with no code.

I'm torn between tracking down the oil leak that has gotten somewhat serious and seeing whether that might be impacting the code, or whether I should take the time to swap the injector from the fifth cylinder to the fourth cylinder to see if the code follows it.

Question about the injector swap: should I get a set of o-rings for reinstall or reuse existing o-rings?? Anything else that I should have on hand if I take the injector rail off?
