Has anyone else run into the problem of your vehicle idle dropping down to 500 rpm when disengaging the clutch?
I know sounds weird as hell but seems every time I am coming to a stop or slowing down by putting the car in neutral the cars rpm will drop down to 500 momentarily then even out at 900. This has been steadily getting worse it used to be every other time it would do this, now does it every time the clutch is disengaged.

Had mine tuned . Mine does the opposite of yours. When i come to a light and pull it out of gear my rmps shoot up to 1300 to 1400 then drops down to 600 to 800rpm then up and down for about 15 to 20 secs, but they said that was normal so i suggust to tune, only if you would like it this way go for it.

P.s I'm looking for a new tuner.
pss might b a vac leak

Vacuum leak or need of an Idle Relearn procedure or both. Pull your codes and post them.
