Odd issue reared its head last night.

Idle is oscillating between 350-650ish rpm at stop lights.

Occasionally dies when letting off the brake pedal at a light.

No codes. No glaring symptoms.

Almost seems like a vacuum leak. Are there common areas that like to cause leaks on these?

SOLVED: good god guys I am so ashamed of the solution. The coupler from my Corsa intake box to the tube, had slipped off, essentially making a giant vacuum leak. Keep it simple fellas, that’s usually the answer
