The car starts very well, hot or cold, idles pretty good when cold however pretty rough when hot. The idle when the car is sitting still is about 550 RPM, but if I let the car roll in neutral 5-10 MPH down hill, the idle jumps to about 2000 without touching the accelerator (note - it also smoothes out).
