Re: 98 3.1 idles funny and sometimes stalls. need help!!!
Your tach is not right. For some reason it seems to be showing a reading that is split in half...a motor won't idle at 200 rpm...800 is typical. I'm guessing it's trying to indicate 400-800 rpm.
A motor will idle at 400 but barely, and not smootly, and not in gear, most likely.
Is this in-gear idle speed or in park? Warmed up it should idle at about 750-800 rpm, and not drop below 600 or so in gear.
Usually a cold start rolling idle like that will be a sticky IAC (idle air control) or a vacuum leak. there are other possibilites too but that's where I'd look first....
You have 2 o2 sensors, which was replaced? It shouldn't be involved, the o2 sensors' readings are not valid until the motor warms up a bit.
Just to clarify, do you mean it only does this rolling idle thing when the motor is cold, or that's the only time it will stall because of it?
