Hello. I have a 97 tahoe (great car, the name in my country is grand blazer), and latelly, when it´s moving and I take out the feet of the gas pedal, the motor stops. I usually put the gear at neutral and turn the ignition key so that the motor starts again. Sometimes it works, sometimes I must stop and try several times before it starts (it all happens with warm motor, and it doesn´t happen all the time).
If the car were an old one, with a carburetor, I would just adjust the "minimum gas" screw, because if I keep the gas pedal slightly pressed, it never stops, but having fuel injection system, I wonder if I must have the injectors cleaned or what else.
Forgive my poor english.

The check engine light is it On?

Have the Idle air control valve and throttle position sensor

No light is On... If I had to make a guess, I´d say maybe there´s some dirty at the gas filter, or at the injectors, but to be true, I don´t know how the injector failure looks like, believe it or not, this is my first car with no carburetor (I had a 1980 Malibu and I loved it so much, I didn´t want to give it up until now)

Thanks

In today's technology-you have to use special tools and equipment to troubleshoot.

Check the idle air control valve/throttle position sensor/exhaust gas recirculating valve and last the fuel pressure.
