Question about 1998 Ford Taurus
Car shuts off after 20 minuits of driving at stops with ac on .
It may be that you need the throttle body and air bypass idle speed control valve cleaned, this is easy to to, pull of the rubber air intake hose off the engine, hold the eng. at hi idle and spray an approved throttle body spray cleaner in, use at least half the can, then lower the idle and spray until the engine stalls, disconnect the battery for 5 minutes to clear any codes and reset "idle learn" system to base line in the Power Train Control Processor. Drive a few days to reset idle learn and this should cure the issue of stall, if not you may have another part failing.
