2G Misfire when warm at low RPM - stock, no CEL

[ErikTande]

Got a 1997 Talon TSi I'm having a misfire / stumble / miss problem with. It's fine when it's cold, but when it's warm it starts to misfire at low RPM and at idle. Higher RPMS seem ok. Car is bone stock.

Plugs and wires have been changed, and I assumed it was the ICM so I swapped that out. No change. It was a junkyard part ICM though so it's possible they were both bad...

No history on the car, I just got it.

What do I check next? Thanks!
