SOLVED: Slightly rough idle, RPM oscillating, occasionally dies…

[KidWgn]

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

No reason to be ashamed. Similar incidents happen to all of us, even if we don't admit it.

That happened to me after I put on my MIT tube about a year and half ago.
I was out of town in a downpour in city traffic...
blocking traffic, all the good stuff !!!
Took me a bit.. Once I got the thing to run long enough to get off the
street into a parking lot.. Then found it !!!!!!!!

If only we all had access to a lift bay for working on our cars.

Can you imagine if those new tract homes in planned communities had an option for a lift bay in a garage? It’d be the frick’n coolest gearhead neighborhood ever.

It’d be like “Yea, bring your car over, we’ll put it on the lift, see what’s going on and turn on the grill.”
