Message Since my Z has been done it hasn't idled right.

Here are the steps that I have take so far:


1) Boost leak test = check
2) Diagnostic codes = 55 no errors
3) New plugs
4) New FPR (and PSI is perfect and rises with boost in 1:1)
5) New Idle Air and checked OHM on Air Reg and took apart. All items are are within spec and looked great.
6) I checked ground on MAF
7) New Gasoline

Profile is up to date.

Here is a video of what it is doing. The odd thing is that the car runs great when I drive it just has the idle that climbs and falls.

Example starts at around 24 seconds in.

I am not touching the gas the entire time in this video.....this is what it is doing on its own.


The pillar gauges from top to bottom:
Fuel Pressure
Boost / Vacum
Oil Temp

It also sounds like it has a slight miss to it at lower RPMs.


I am out of ideas on this one....any help is greatly appreciated
