Re: stalls intermittently, wrench icon lights up under...
Problem with the electronic throttle control .
It should be noted that the ETC system includes a wrench light on the instrument cluster that illuminates when a fault is detected. Faults are also accompanied by DTCS and the "Check Engine Soon" light. Your best bet is to take your vehicle to a reputable ASE certified repair shop .
Overview
The Generation II (Gen II) Torque Based Electronic Throttle Control (ETC) is a hardware and software strategy that delivers a transmission output shaft torque (via throttle angle) based on driver demand (pedal position). It utilizes an electronic throttle body, the PCM and a accelerator pedal assembly to control throttle opening and engine torque. The ETC system basically replaces the standard cable operated accelerator pedal, idle air control (IAC) motor, 3-wire throttle position sensor (TPS) and mechanical throttle body .

If you are in Limp Mode, the scan tool will tell you why?
If the battery light is flashing on and off, you have a battery issue, a wiring issue or you have an alternator charging issue.
All your faults can be diagnosed cheaply by an auto electrician using a Professional Grade Scan Tool COMPUTER. This is not a normal $125 scan tool. They cost between $3.5k and $5,000. Employing an electrician in far cheaper than guessing parts to swap out, test always, then replace.
