IGOTGAS

To bring my Stang into the dealer for service, I removed my CAI and catch can, and used my SCT tuner to "return to stock" so the ECM is not running a custom tune anymore.

On my way there the car stalled at idle, I drove around more for 20 miles or so without issue, then the dealer called to say it happened to them too. I told them I have no idea why it would do that.

It seems to idle very low, around 500 rpm, but with everything back to stock, should I pull the negative battery cable so it can recalibrate everything, or is there something else going on here?

Any help is appreciated.

Thanks!
