high idle and sterring pump nosie
I have a 1990 v6 4x4 4runner. I'm in dallas tx and last week it's been a bit cold in the morning, around 55º. well, my engine reves up high around 1700 rpm and stays there for 10 mins of driving. My power steering pump also makes a noise for about 10 mins. after the truck is nice and warm eveything is fine, no noise and the engine idles fine. today it was abot 85º when i turned on the truck for the first time in the day and the idled was up to 1100 rpm and then it when down to 900 after may be 2 mins. The power steering pump didn't make any nosie. before it started to get cold the truck would idle fine and the pump wouldn't make any nosie. I just changed my spark plugs, wires, cap, rotor, 02 sensor, air filter, fuel filter, i've cleaned my intake. I checked the steering pump fluid when the day is cold and it's making that nosie it looks like foam in there. when the day is warm it looks fine. Why is the engine revving so high, I try to keep it tuned and she runs very nice. I can't even feel the engine on once its warm. i can understand the pump is getting old and it may need to get warm to work.
