I have been reading and researching for about two months on this problem and have come up with nothing. Its my dad's 04, 305 motor, 4x 6spd. All he has done to it is a 6 gun with a speed loader and an after market Walbrow lift pump.
The truck will crank up and run fine. If he rolls to a stop the motor will idle at about 1000rpm. If he lets out on the clutch to give the engine a slight load it will drop down to 750. Even a load as small as turning on the A/C compressor brings it down to 750. Its been doing this for a good three months. Only code he has is 483 for cooling fan speed. Fuel and air filters get changed on a regular basis (usually every other oil change which is 7k). Any ideas?
