That's how most generators are designed so you don't damage anything running below the reccomended rpm. Some are equipped with an idle switch on the control panel so you can properly warm up and cool down the engine, but that's idiotic in my opinion they should ALL have that feature to prolong engine life. If you're concerned, an can reach it, hold the governor down so it forces the engine to idle for 20-30 seconds before and after use, but most things are made in china nowadays so who knows how long it will last even IF you did that anyway. Change the oil when it gets dark and keep the air filter clean. And make sure to drain all the fuel when you store it and run it dry so the carb won't get clogged up and you'll be fine atleast for a few years. You should listen to me, I've been doing this a while.

Starting Mode
With the ignition switch in the ON position, before engaging the starter, the PCM energizes the fuel pump relay for 2 seconds allowing the fuel pump to build up pressure. The PCM first tests speed density, then switches to the mass air flow (MAF) sensor. The PCM also uses the engine coolant temperature (ECT), the throttle position (TP), and the manifold absolute pressure (MAP) sensors to determine the proper air/fuel ratio for starting. The PCM controls the amount of fuel delivered in the starting mode by changing the pulse width of the injectors. This is done by pulsing the injectors for very short times.
Clear Flood Mode
If the engine floods, clear the engine by pressing the accelerator pedal down to the floor and then crank the engine. When the throttle position (TP) sensor is at wide open throttle (WOT), the PCM reduces the injector pulse width in order to increase the air to fuel ratio. The PCM holds this injector rate as long as the throttle stays wide open and the engine speed is below a predetermined RPM. If the throttle is not held wide open, the PCM returns to the starting mode .
You could have a dirty or bad mass air flow sensor .

Throtle gets stuck wide open i did tps worked for a day always pump to start runs ruff then goes bamm gets stuck wide open help me


You should not need to pump the throttle. That does not have any effect on starting the engine on a fuel injected car.
How do you un-stick the throttle ?

Wide open as in wide open throttle?? You mean the engine is racing? Something is wrong with the throttle controls, or the throttle valve in the carburetor may be sticking open. Look down the carb throat. At its base will be the throttle valves-"butterfly" valves just like the choke valve on top of carb. The throttle valve should be closed at rest, or at idle, or when gas pedal is not moved. Rotate the throttle lever on the carburetor by hand (when gas pedal is pressed down, the throttle is rotated). The throttle valve at the bottom of the carb should open and close with the throttle lever.
If the valve is sticking, spray some carburetor cleaner down it, and spray the outside clean, too. Work the throttle back and forth to make sure it is free to move.
For a high idle, have the carburetor adjusted. Timing should be checked, too-that can cause a high idle, but wouldn't cause it to go wide open.
Let us know what you find. Good luck.

The F1 light is an engine management error, take it to your nearest dealer and get them to run their diagnosis machine on it. You may have a mixture problem or an ignition timing problem.

Had 2 problems occur at same time after some repair. 1st. After repair started up an engine runs wide open with no throttle .Checked an cleaned T>P>S. an throttle body . Checked for vacume...


The only way an engine can run Wide open is if the throttle plate is opened all the way, allowing a large volume of air in to the engine. Check the throttle plate and see if it is hung up or possibly the throttle cable is frayed and holding the throttle open. It is not the injectors, they operate on inputs from the PCM.
