99 Tacoma Six Cyl. Stalling During Idle at Traffic Lights

Had a tune-up and a mechanic also looked at the accelerator pedalfor some reason, but no report regarding the fuel injection or regulatory components which I suppose should have signaled an issue when the computer diagnostic was run if I am to understand the mechanic’s position.

If you keep the accelerator pedal down a bit will that keep it running? If so then the idle air control (IAC) valve should be checked.

Thanks - I will definitely get a response from the mechanic.
