Thanks, this is super helpful and informative. If an injector is in fact leaning out (on either #2 or the opposite cylinder) is there harm in running the engine for hundreds of miles through multiple tanks of gas to get these cleaners/lubes through the system? Am I at risk of burning a valve here by continuing to run it or would the engine computer continue to intervene before damage is done? Is it smart enough to throw a misfire on a "kinda lean" condition on one cylinder? I don't know if I'm making sense here but I'm worried about running the car more, I guess.
Your code is for a misfire, but without turning off the fuel. Can you even feel it? Does it even set a light? If yes does the light turn off on the next start? It may not be going lean it might be rich. Depending, it is more common for the injector to not close which causes rich. But there is no real way to know. You could try watching live data but that is what the DME does and if it sees a fluctuation in the O2 readings it will shut the fuel off to that cylinder.
Since the DME can't see anything in your readings I doubt you or I could either. The DME sees all, we only get to see a smoothed effect, do to reporting to the scanner being a tad slow.
Don't really have an answer to the question but it is not a dangerous misfire or the DME would shut off the fuel.
That said my advice would be gentle, then do a hard pull to see what is up. Gentle, at a 1/4 tank gone do a hard pull to see if things are different, repeat every 1/4 tank. But be gentle in between, just not so gentle you can't feel any difference.
Is that vague enough for you? Lol Sorry no real answer there is a risk when things are not right, but I have no way to know. You will have to judge for yourself and live with your decision. You could just run out and buy 8 new injectors, that is what I would do if I found a problem with one 15+ year old injector. I would not send them to be cleaned just replace.
But you still need to see if it might be injectors, what is causing your miss is still up for debate.
Hope this vague non committal answer helps in some way.
