Was backing out of the drive way with my 6 speed R/T today. The car had been in the garage in the house. So it wasn't that cold . A contractor working on building a house across from me had a truck and trailer in our street across from the drive way. I backed out slow and careful . When I stopped to put the car in 1st gear . The idle was 2500 rpm with my foot off the gas . I hit the pedal and it went to 3000 and stayed there with my foot off the gas. What ??? . I let the engine warm up for a minute or two with the clutch in . Still didn't come down. So I turned the key off . Then restarted it and it was ok . Anyone else had this . I've thought a few times the engine jerked when changing gear's . I stopped and talked to the local dealer and was told first they had heard of this problem. They will if it happens again .
