k20 jumping ignition idle

Post by forryk »

Hey guys,

I'm having some issues with my supercharged k20 EP3.
So basiclly the ignition jumps between 5-30* at idle it wont hold steady... So the car "sputters" backfires at idle.

I tried a known working set of coils and traced all wiring, no issues.

What is shown in the datalog looks pretty normal as it has ignition controlled idle.

No, it will move around to help maintain a steady idle.
