I have a 2004 1.4 liter rear wheel drive Toyota Tacoma. Starting up the car, the idle is on steady. But when reved, either idle goes low or car dies out. When driving as well, when put on neutral, the car will die out and have to start it up again. What are some causes of this problem and what can be done to avoid car from low idle and dying out?

First eliminate all vacuum or air leaks in the system (very important)

. You may have a bad IAC ( idle air control) but try cleaning the throttle body first. Remove the intake snorkel, have someone hold the throttle wide open for you and scrub the back side of the throttle plate and surrounding bore with an old tooth brush and some carb cleaner. Be sure to spray some into the small holes next to the throttle plate. That should help stabilize the idle. If it still has a problem, replace the IAC.
