Engine cutting out while Breaking
I have a 1996 Jeep Grand Cherokee Laredo with the 5.2L V8 engine and have been having a problem with the engine cutting off when i start braking. The electrical will stay on but the engine dies.
Any ideas what is causing this?

IDLE AIR CONTROL (IAC) MOTOR—5.2L/5.9L
ENGINES
To perform a complete test of the IAC motor and
its circuitry, refer to DRB scan tool and appropriate
Powertrain Diagnostics Procedures manual.
THROTTLE POSITION SENSOR (TPS)—5.2L/5.9L
ENGINES
To perform a complete test of the TPS and its circuitry,
refer to the DRB scan tool and appropriate
Powertrain Diagnostics Procedures manual.
To test the TPS only, refer to the following:
The TPS can be tested with a digital voltmeter.
The center electrical terminal of the TPS is
the output terminal.
With the ignition key in the ON position, check the
TPS output voltage at the center terminal wire of the
connector. Check this at idle (throttle plate closed)
and at wide open throttle (WOT). At idle, TPS output
voltage should be greater than .350 millivolts but
less than 900 millivolts. At wide open throttle, TPS
output voltage must be less than 4.5 volts. The output
voltage should increase gradually as the throttle
plate is slowly opened from idle to WOT.
