Re: Power Steering Problem
I would guess something is wrong with your IAC (Idle Air Control) valve. As your turn your wheels, the power steering pump loads up... causing the engine to instantly slow down. The IAC, along with the PCM and the crank sensor, are supposed to compensate and keep the idle rpm pretty much constant...unless your ps pump is really a basket case.
It will take several ps reservoir changes to get the fluid in good shape... and it never will be "pretty". I change mine at every engine oil change. I use the synthetic blend stuff by Valvoline... tho it probably does not meet Ford spec.
