With a voltmeter, check the TPS on your throttle body. Your volt setting may be off too. With a Phillips screwdriver, you can adjust it to 0.8V (Is this it guys? someone please verify this setting, and help out XBAJBUSX! thanks!)
Happy Stanging!

key on, engine off, (KOEO) 0.995-.998 D.C. High TPS voltages
are characterized by a very erratic idle or stalling when coming to a stop (ECM error code 66). Set the throttle by
removing the connector from the Idle Speed Control Motor, with the engine warm and the air conditioner off, using the
throttle screw set the Idle Speed at 700 RPM ( or desired RPM). On '94 and later models use the idle bypass screw
at the right side of the throttle body covered with a plastic cap. Reset the TPS to obtain 0.995-.998 volts D.C.
between the black and green wires on the throttle pot. If the unit has no voltage, check the voltage between the black
and orange wires. This should be 4.9-5.1 volts D.C. with the ignition on. If the voltage is 4.9-5.1 D.C. and there is no
voltage on the green wire, the throttle position sensor is no good. If there is no voltage on the orange wire, you must
find a break in the wire. Reconnect the Idle Speed Control Motor and check for engine stability
DONT GO OVER 1.00!!!!!
