I get the car home and immediately run the codes. It's a p0175, p0300, p0305, p0306, and p0308. Basically I have a misfire on bank 2, cyls. 5, 6, and 8. My thought is an injector failed, flooded the cylinder, and fouled the plug. I do not think 3 injectors all of the sudden failed. That would seem implausible.
My question is really 2 fold. Can someone, specifically explain, how to pinpoint the faulty
Injector, and I've read that the the car takes special injectors. I don't know the series on mine — I know OP has series 11 — as I've never had to look. Can OP or anyone offer any guidance.
BTW, most of the links in the original post no longer work.
