When cold, car will start and idle fine @ ~1100rpm. After a minute or two it stalls. After it stalls it will crank, and fire, but stall instantly once it catches. After doing this a few times it will crank, but wont fire until it's cold again.
It's not:
Fuel filter (replaced)
Fuel pump or ECU (no change with b+ and fp jumped)
MAF (no change with MAF unplugged)
with heavy throttle while warm it will fire and rev like hell, but sounds ugly and rpms will cut out to near stall and jump back up intermittently, sometimes stalling.
I'm thinking the driver side coil dies when it gets hot, anything else it could be?
Plugs, wires, caps, rotors all replaced 3 years/20k miles ago during tb/wp job, coils are original @ ~150k miles.
Thanks all.
