It is possible the throttle body butterfly is sticky and not opening correctly. To fix it get a throttle body brush($1.99 at the store) and clean the carbon or dirt out of the throttle body. You can get to the butterfly through the air intake. screwdriver removes the hose clamp. Use a degreaser like crc or brake cleaner to clean out the exact area where the butterfly seats and scrub the area with brush. When you start it it will smoke and smell funny for a minute then clear up. This is common on a lot of Fuel injection systems. 5 minute job

The electronic throttle control light stays on when the engine computer detects a malfunction related to the throttle system. You need to have the system checked for codes to know possible causes.

what causes air injection system pressure to be stucked in cars
what causes my thunsercat to jerk in all gears on a steady throttle?
The first step is having the computer checked for codes. When you know the failure code you can diagnose for possible causes.
The TPS (throttle position sensor) has gone bad on your throttle body.
Damage to the throttle body is caused by corrosion or direct impacts. A loose connection can cause nearby components to strike and damage the throttle body.
the camshaft timing will cause the late injection process
The heavy rain flooded the river. Here the heavy rain is the cause the effect is the flooded river Cause and effect is the result of something that happens
If it's repeatedly flooding, you need to have the carburetor rebuilt. At the very least the needle and seat are leaking and possibly stuck open. If it runs well most of the time and it just floods occasionally, hold the throttle to the floor and don't let it move while you try to start the engine. When the throttle is part way up, the choke causes a lot of fuel to be drawn in, flooding the engine. When the throttle is all the way down, the choke opens up a bit, letting more air in and cuts back on the fuel. Also, every time you step down on the throttle, you pump a little more fuel into the engine, so if it's flooded, just hold it down and don't let the accellerator pump make it worse.
its the sound of the pistons stroking.
you probably have a worn out throttle cable. replace as soon as possible before you have a wreck. they are usually $20.-30 for new one.
It means that the computer has detected a malfunction and set a code. You will need to have it checked with a scan tool to know possible causes.
stuck throttle butterfly plate
Possible causes, mixed up spark plug wires, wet/damp spark plug wires, a bad distributor cap and/or rotor and a burned intake valve could cause the 4.3 to pop through the throttle body.
some possible causes are careless and..............
Perhaps a stuck throttle plate - try to free with a screw driver The throttle position sensor is also notorious for causing this as well. A vacuum leak can also cause high idle speed, but the vehicle will generally run rough as well.
its the throttle position sensor
A dirty throttle body will cause that.
Your throttle linkage may be sticking. You can try spraying it with wd40 to loosen it up usually near the carburator.
You know how when you press on the gas pedal the car goes faster? The throttle is the part of the engine assembly that opens to let more air into the engine and simultaneously sends in more fuel, thereby making the engine put out more power, making the wheels go faster. On injected vehicles an air valve assembly is connected to the throttle mechanism to allow more air when the gas pedal is pushed. At the same time, a throttle position sensor determines how much you have pressed the pedal and the computer, sensing the positon change, causes the injectors to deliver the appropriate amount of fuel into the throttle-body or manifold (depending on the type of injection system).
That is one of dozens of possible causes.That is one of dozens of possible causes.
poor timing of the dye injection, the way in which the pathologist prepared the tissue for examination, or the existence of previously undiscovered sentinel nodes.
