im new here but mine does seem to have a problem. while in neutral/ idle it stays at 900ish some times it goes to about 700. when i stick it in automatic/ first gear it drops below 400 and makes the car judder/ kangaroo (does the same in reverse as well but if i use the throttle a little to raise the rpm to anout 800 - 900 it cuts it out anyway of making it stay at 900?? to stop me from driving my little forfour into a truck.........
