SOURCE: running rough
could be the idle air control solenoid , its right below the throttle position sensor(opposite where you can open the throttle with your hand) on the 3.3v6, when that goes it does all sorts of stuff, bottom line its going to have to be put on a dyno to see what it is but you can take that part off and get one at the junkyard we got a whole throttle body for 10.00. Try also to disconnect the electrical connector off the idle air control solenoid and see if runs any differently, then youll know right away

SOURCE: LOSING POWER AT IDLE.
In such a situation the TPS Sensor must have gone bad.
Have a check first, run a scan and if the code says error 7 for OBD 1 and P0120 or P0121, then it is the TPS Sensor.
Cheers and dont forget to rate this.

The fact that you get enhanced ignition by physically enriching the fuel air mix indicates that the normal mix is too lean, either too little fuel or too much air. 1) Check for leaks of un-metered air in to the air ducting and inlet manifold. Look for cracks and poor joints to all vacuum lines including the evaporative emission recovery lines. 2) Check that the EGR valve is closed off at start up: this should stay closed until engine has warmed up. 3) Finally check that the coolant temperature sensor is working OK; the sensor should be informing the ECU that the engine is cold and the ECU responds by ensuring an enriched fuel mix (by prolonging the injection cycle) during engine warm up.

Testimonial: "Very helpful. "
Could be a wheel speed sensor going bad and making the computer think it is spinning or losing traction causing a power reduction to reduce spinning.
