2005 PT Limited...4 cly, automatiic...

Hicup in gear at idle....rougher w/ac....seems to be after about 10 seconds at stop...Seems to be intermintent......but mostly semi rough when it occurs...will repeat about 5 seconds between occurnances....when it happens..(If bad wires or plugs would this not be constant)...??? Puting into netrual does't seem to effect the stumble...
When giving gas after stumble or rough idle the Pt will take off without any stumble and will wind up to at least 4500+ rpm without any problem..
85,000 miles on PT...
hesitation after idle at stop...
new plugs at 75,000, with oil and oil filter change, and new air filter....at time of service complete running ok.....(Serviced at a Local Goodyear site) prior to this service ok with no problems....after about 2,000 miles starting to run rough.....
pcv working seems to be working ok......
use for courier service about 200 miles per day.....1000 miles per week mostly highspeed interstate...
gas mileage still good at about 26.5 ..........
no codes indicated by turning key on with odometer pressed...shows all but error codes...
no check engine light on....
slight stumble at about 50 mph on gear slection ......
Hot or cold weather doesn't seem to effect this condition...
any sugestions on what may be the problem would be a help to me...
thanks. PTEuclid.....
