Hello I am experiencing problems with a 2000-2001 mercury sable dohc 24 valve I believe v6. when it has warmed up and is idling it will die down to about 500 or below rpms and spit and sputter there and hit the gas and it jumps up runs fin for a min and goes back down below 600 rpm and sputters.. umm don’t seem to do it when driving.. check engine light has came on in past once in awhile saying bank 1 is running lean and rich?? I disconnect front bank spark plug wire connector when it is sputtering and dose not make a difference any advice or question would be very helpful thank you..
