Stalling / limp mode / no CEL

[Epoustouflant]

Hey guys,

I have experienced stalling at a stoplight tonight.

Car went into limp mode & stalled. Starts back up with no codes / CEL - then it stalled again. Fired it back on and drove away, didn't stall again, though I avoided full stops.

ICV was changed 3 weeks ago. TAs have been done recently. Fuel level was just a tad over 3/4 of a tank.

I am guessing fuel breather valve, or fuel pressure sensor.

Anything I'm potentially missing?

Bouncy revs? Did you recently add fuel?

Mmm, it was at 3/4 of a tank - no bouncing.

I'm below half now, got CCID29 on an on ramp, limp code without the limp.

Recently changed the ICV. This seems to be a plug or coil issue.

Update; hasn't come back yet. With the upcoming cf plenum, I've decided to just throw parts at the car anyways 🤪

Fuel breather valve, air intake sensor, and low fuel pressure sensor.

Consider changing upstream O2s. Cheap and quick. At least check them to ensure they're not loose.

O2s on primary cats?

Yeah, upstream of the primaries. Least just check... They can fail and throw 2B0D related codes without throwing O2 specific codes.

Got it. I'll get the codes pulled, hopefully they're stored.
