[Shotimes] Leaky FI ~

[Ron Porter]

If it was leaking, it should run worse on a warm motor, as the fuel needs
diminish. Running in open-loop when it's cold adds more fuel anyway.

Maybe the chip program is running it a bit rich, and cold open-loop mode
accentuates that

Might just have one sticking a bit. The toluene could help that.

When I add unmetered air the idle improves.  If the car was running lean it
would stumble more with the additional air,  Or so I suppose.  If I open the
throttle at all the stumbles go away too.  Plus this only happens on a cold
motor.  Once the car has been driven and heated up it runs and starts fine.
I'm thinking about adding a heavy dose of toluene.
