Customer Question

Just had transmission replaced. Cold start engine idols at about 1k rpm for 30 to 60 seconds, then idol varies between 2k and 700 rpm every second and a half or so and this lasts about 30 to 40 seconds, then it will rev to about 1500 and cycle between 1500 to 1200 RPM about two of those cycles per second and continue doing that until I put it in gear. But even in gear, while I'm driving and let off the accelerator I can hear the engine doing the fast cycling while not under a load. What could be causing this? Thank you so much!
