What I thought was #2, is actually #3. I was using the old numbering system, not the correct one. So, in fact #3 has been misfiring the whole time. My scanner called #3 coil bad, so it's been replaced or swapped multiple times. Coils and injectors have all been moved around to no avail. I have not changed spark plugs, nor have I inspected the upper intake for a blockage. The second one, I seriously doubt has an issue.Can we just recap to confirm which cylinder is misfiring, and to what extent?
In post #58 you mention cylinder number 2 is the only one that doesn't sound any different if you unplug the coil, which would be number 3 with the later numbering system. ignoring numbers, this would be middle cylinder, right hand bank, yes?
Since the person that messaged me about buying it has ghosted me, it looks like I may be putting some more money and time into the car. I didn't want to spend too much of either if I was going to sell it quickly.
Thanks again everyone, I hate getting my arse kicked by an inanimate object.
