Problem with rough idle

Asked by Aug 24, 2014 at 10:13 AM about the 2000 Mercury Sable LS Wagon

Question type: Maintenance & Repair

I have a 2000 Mercury Sable with a 3.0L DOHC V6 Duratec engine.  Sometimes at cold start up it run really rough and will cause the check engine light to come on.  I have taken it to a parts store and they hooked up the computer to the car and it states that there is a #3 misfire.  Can you please tell me which bank the #3 spark plug is located on.

Cylinders 1 2 3 are against the firewall. Does it blow white smoke when first started? Are you loosing coolant? I would have a concern about a blown head gasket.

No it is not blowing white smoke or loosing any coolant. Thanks for your answer regarding where #3 is.

I heard this was caused by problem with air idle bypass value. Also loud horn like noise when cold engine.
