RE: Car dies!!!!!! Help!!!
Idle Speed Control Bypass Air (ISC-BPA) Valve Cleaning
WITH SPECIAL TOOLS
CAUTION: DO NOT use the following procedure on a Nippondenso ISC-BPA valve (black plastic), as damage may result. Nippondenso valves are serviced by replacement only. Use only spraycarb cleaner (Ford D9AZ-19579-BA, or equivalent). DO NOT spray directly on on throttle plates or use any type of scrubbing method. If the vehicle is equipped with a Mass Air Flow (MAF) sensor, do not run the engine while cleaning the Idle Speed Control By-Pass Air ISC-BPA valve.[*]Remove the throttle inlet air duct.[*]Disconnect the ISC-BPA valve connector.[*]Connect the ISC-BPA actuator (Rotunda 113-00009, or equivalent) and the injector tester/cleaner (Rotunda 113-00001, or equivalent) to the vehicle.[*]START the actuator and then START the engine (non MAF engines only).[*]Spray carb cleaner (Ford D9AZ-19579-BA, or equivalent) into the ISC-BPA valve for five seconds while actuator is operating.[*]Turn OFF the actuator and STOP the engine (if running). Allow the solvent to soak for 15 minutes.[*]Turn ON the actuator and START the engine (non MAF engines only).[*]Spray carb cleaner into the idle ISC-BPA for up to 6 seconds (MAF equipped) or 1 minute (non MAF equipped).[*]Turn OFF the actuator and shut OFF the engine (if running).[*]Install the throttle inlet air duct and START the engine, allowing to run for 1 minute.[*]Disconnect the actuator from the ISC-BPA valve. Connect the ISC-BPA connector.[*]START the engine and check for proper operation.

CAUTION: DO NOT use the following procedure on a Nippondenso ISC-BPA valve (black plastic), as damage may result. Nippondenso valves are serviced by replacement only.[*]Remove the Idle Speed Control By-Pass Air ISC-BPA valve from the throttlebody.[*]Remove the electrical solenoid assembly from the mechanical portion of the ISC-BPA valve by removing the two screws, then sliding the mechanical portion away from the solenoid.[*]Soak the mechanical portion of the ISC-BPA in carbcleaner (Ford D9AZ-19579-BA, or equivalent) for up to 3 minutes. CAUTION: DO NOT exceed 3 minutes soaking time and DO NOT use choke cleaner, as internal damage may occur.[*]With the mechanical portion completely submerged, shake in all directions (up, down, right, and left). Push in the on the rod that mates with the solenoid assembly and again shake in all directions with the rod pushed in as far as possible.[*]Remove the valve from the cleaning fluid and dry it out with compressed air.[*]Reassemble the ISC-BPA valve and install on the vehicle, torquing the bolts to 71-102 lb. in. (8-11 N-m).

R u running MSD and a crap load of other stuff from your battery. I heard about this on another forum. It was that guys battery having some issues. As long as the RPMs were up he ran fine. But then it would die or idle like crap when he left off. He changed the battery on a whim. And fix the problem. DUNNO. Everybody else covered everything else. I hope you figure it out.
