Check to make sure the belt it tight and not slipping at idle. After that try a fluid change. If those things do not fix the problem then you need a new Power Steering pump.
Check your power steering fluid
If you are talking about air bubbles in your power steering fluid?. The supply line to your power steering pump has a bad o-ring. This will cause you hard steering while engine is at idle.
weak power steering pump, or worn rack and pinion. 65;
The power steering output is directly proportional to the engine speed [RPM]. I suspect that when it is difficult to turn, the engine is at idle speed, which is set too at too low an RPM. Then when you depress the accelerator, the engine speed increases and the power steering pump speed and output power increase also. Have a qualified mechanic check and properly set the engine idle speed to the manufacturer's specifications. IF the idle speed is not abnormally low, would suggest a badly worn power steering pump. Properly set idle speed first, and if that does not correct the problem, then have the power steering pump output checked.
Depends if at idle without any force on the steering wheel or with force as bottoming out. Normally 350-1500 pounds.
if it doesnt idle what does it do..... it prob idils rough. change power steering pump and or rack and pinion steering assembly if ur rack is worn it will burn up pump
Possibly, the power steering pressure switch changes the idle if there is more pressure due to use of the power steering it will increase the idle. A bad switch could be sending faulty informatioin causing your idle to be wrong and the car could stall. These switches cost about $30-$35 and depending on location take minutes to change with a couple wrenches.
There are no coolant lines to a power steering system so the only two ways I can imagine water could get into it are from someone accidentaly putting water in the power steering fluid reservoir or a vehicle sitting idle for a long time with the cap off the reservoir and possibly no hood.
Your car most likely have power steering, and the power to the power steering comes from the engine. So when you turn the wheel, the engine has to work a little harder, and to work harder the engine has to spin a little faster.
Toyota 5K engines idle are: without vaccuum hoses attached but sealed = 750 rpm with attached vaccuum hoses and power steering = 850 rpm with aircon on and power steering attached = 900 rpm actually i run mine 5K toyota at 600 RPM with power steering but without aircon. With aircon on it should be at 800 RPM. or else its gonna be shaking. Ricky Recodo
sounds like the power steering pump is losing assist at idle . At best a loose belt. Check fluid level
Sounds like the power steering pump is going bad. Check the fluid leavel
