My 1997 infiniti truck model qx4 is idling high when I put it in drive it takes off without me pressing on the gas when I try to slow down it will allow for me to slow down to 10 mph but it speeds back up on its own making it impossible for me to stop so I had to put my car in park and brake smoke came from one of my tires. What is the problem Infinity QX4

High idle speed is typically caused by a vacuum leak. Check the vacuum hoses first. If you don't find any that are cracked or broken spray water over the engine while it's running and still cold. Watch for places it gets sucked in.
