I have a 2015 EB just hit 50k on it. The only thing I've done to the car is CAI (put it on right after I got it.) Having an issue when I first drive for a little bit it will dip in RPM's for a second (every 15-25 seconds) when I'm sitting at a light. It seems to clear up by the time I get to work (about 45 mins away) Just started about 3 weeks ago. Any suggestions?

Mine does this occasionally too - it actually stalled once! I have yet to figure out what causes this.

How much of a dip we talking? Can you just feel it or do you physically see the needle dropping

Not sure about the OP, but both for me. You can feel the car shutter and see the RPM drop.

It runs pretty crappy for a second or two (enough for me to feel it) and I can see the tach drop and pop back up.

when i had my '15 EB I experienced this right after a fillup. It would cease once I drained the tank a little bit. Does this happen with you?

Actually it does happen mostly after I've filled the car up now that I think about it. Seems a bit odd.. I have some new plugs at the house was hoping that would fix it.

TBD
Have your EVAP system checked. Also have the intercooler checked. If you have a catch can, make sure you've emptied in recently.

I was never able to figure it out before I traded it in, chalked it up to something to do with the vapors from a full tank...:shrug:
