Question about 2003 Hyundai Tiburon
My 2003 Tiburon with a 2.7L v6 will crank and run, but idles low and will not respond to throttle. In the past while driving, the car would occasionally jump or sputter and then continue, but now while driving there is a complete loss of power, no engine rev at all when the throttle is pushed, any ideas as to what could cause this? Also, check engine light was on last week for a day but went out...
First thing that comes to my mind is a vaccum hose. My girlfriends car did this and i fixed it with a piece of 3$ hose. If the light is on you can take it to your local parts store and they can hook it up to a device that gives them the trouble code. They can then tell you what is wrong with it. Do not let them sell you any parts until you confirm that this is the problem. They sold my g/f a 300$ mass air flow sensor when the vaccum hose was all that was needed. Have a friend rev up the engine while you listen for a whistling noise under the hood. If you hear one this could be your problem. You could also have electrical issues such as a bad coil pack.

Engine stalling and rough run
issue at low speeds
is commonly caused by a dirty automatic idle speed control valve and
throttle valve. Buy a can of throttle valve cleaner (do not use
carburetor spray cleaner!) from NAPA or Carquest (made by CRC
chemicals) and spray it into the air intake while the engine is
running, use up about 1/2 the can, engine will try to stall hold the
speed up, shut it down and let it soak for 30 minutes, restart and
blow out the remaining fluid, shut it down and disconnect the
negative battery cable for 5 Min's to reset the base idle control. If this doesn't improve the problem you have mechanical problems in the engine like a low cylinder die to worn rings or leaking valve seats.
