05 Ford Taurus , 3.0L , Vulcan motor. Here is the problem. When starting up cold the rpm rev up of course but after it gets down to about 800 rpm the car starts to idle very rough. Seems to get better after car warms up. Some times it takes a long while to run smooth. Ideas??

finally got codes. One question though.. Can these symptoms also be caused by a vacuum leak> Codes are p0303 and p0301

Those are indicating misfires in cylinders 1 and 3. Vacuum leak is not real likely with those. Bad coils are more common. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.
