N54 rough idle

[John6857]

So you've been having a rough idle for a few months? When exactly did you first notice this?

If i remember correctly it was after my fuel it stage 2 bucketless pump was installed by my shop.
Not 100% sure i'm pretty sure thats when it started

From my understanding my shop has never installed a bucketless pump, so maybe they messed up something with the install.

I had OE plugs but i started misfiring so i went NGK

And how many miles on the car? If 100k or over, have all 4 o2 sensors been replaced?

I have been paying more attention to my rpms at idle and they have been moving around a little so something is definitely up, i just can't figure put what it is.

Then we need a vid of what your actually concerned about. Those bottles of water look like anything but a Rolls Royce idling..
