Hello Friends, Thanks for your answer. The display show the code e-23.
the serial number is AT3500048


The past thursday, i tested on the machine some things,

i retired the pipe that go of the air filter for see the behavior of the throttle acelerator, and try starter the motor, when see of surprise the motor run, but i should drop the pedal of acelerator for that the motor follow running, when i drop the acelerator pedal, the throttle too is go to close, and the motor is off.

i was Making some attemps, but the motor is ON only for five seconds, i was think that had a problem with the low revolutions, and in the vaporizer i looking for the duct of low rpms, but i dont find this

Then i revised the reductor and find a valve near of the injector, and i think this control the gas that get into the motor at low rpm. I measure the voltage in the wires of this valve when the key is ON position and have 12 volts, but when i connect the valve the voltage drop to five volts, i retired this valve of the motor and see it behavior, when the key is ON position the solenoid is atracted and when the key is OFF position the solenoid is released, some times the solenoid not is atracted although the valve have five volts.
How works this valve?

I have other question, when the acelerator pedal not is push, the throttle should close?
I was think that the body throttle work how to carburator on gasoline car, but i detailed that the duct dont have any holes, then this throttle is with a valve, control the pass of glp and air, this is right?

What do you think about this? i dont see what is the problem

Thank for all and sorry for my bad english
