Weak idle / dying after start, 2000 Town Car
I have a 2000 Lincoln town car that recently started to have an issue of dieing immediately after starting. If I apply throttle right after start, it will stay running, but if I lay off the gas it with die more often than go to a weak idle. It runs fine when gas is applied, it doesnt vibrate or misfire at all from what I can tell and highway speeds are just fine. Just after starting or coming to stop does it either idle weak or outright die.
I have changed the fuel filter and sparkplugs as it recently passed 110K miles.
My father in law has equipment to measure gas pressure which I will be doing sometime this weekend, any other ideas of what to look for? What about the idle control valve? I pulled the electrical connection off it when it was at a weak idle and there was no difference. Could it be that part has failed and needs replaced since there was no change when the electricity was pulled off it??
