[DML] Re: Couple Questions- Coolant System & Idle

["David Teitelbaum" <jtrealty@xxxxxxxxxxx>]

It will hunt more during idle at warm-up while the Lambda is in fixed
mode. Once it warms up and goes into closed-loop it usually gets a lot
smoother. Vacuum leaks seem to make it idle worse. To bleed the
cooling system you really need a coolant presssure tester. Make sure
the header bottle is at least 1/2 full and pressurize to around 10
psi. Loosen the bleeder screw on the thermostat housing and let the
air out. Recheck the level in the header bottle and now CAREFULLY
loosen the small hose on the top right side of the radiator. Let the
air out. Recheck the level in the header bottle. If you keep getting
air in your system you have coolant leaks.
