Random stall when coming to idle - ZR-1 Net Registry Forums

-=Jeff=- · 09-27-2021

So I have been fighting with a stalling issue. If I am coming to a stop, I usually put it in neutral and coast as I slow down. Every once in a while, the car will stall. Just drop out. It will restart and be fine, usually for the rest of the drive. Just not sure where to look next.

I have:
New O2 sensors
New injectors
New coils
New wires
Plugs are about a year old
New fuel filter
Phil's fuel regulator

I don't seem to have any vacuum leaks
Fuel pressure is solid

Outside of the stall when coming to idle the car runs great

Thoughts on where to look next?
