Any Idea what would cause my S80 to al of a sudden only at idle speed surge?? alomost stalling then recovers to 1200 rpm then down then up then down? I disconected the Battery now seems to be a alittle smother!!!

 

Try cleaning the throttle body and see if it helps.

 

Is this a simple job?

 

It is not to bad. The throttle body is under the intake manifold.

 

So I need to remove the Intake manifold?

 

No you do not. Is it turbo or Non?

 

Twin turbo

 

There is a hard plastic pipe from the intercooler to under the intake. You need to remove that pipe. Where it connects under the intake is at the throttle body. Then remove the throttle body and clean it. You will need to get a gasket first.

 

Great thanks a lot I will try tommorow

 

Let me know how it goes.

 

well took it off and disconected the wire. pulled her out and cleaned it up just a little juicy looking carbon in side but there is some evedence of oil in the intake pipes is this normal? After assembly start and run it and it seems fine but I will let her run to get hot and see what happens.

At the same time I here a motor whine from the power steering pump and or the alternator. I use a screw driver to my ear to listen and the sound seems to be equal from both the alternator and pump how can I tell?

 

Well pulled it aff and cleaned a little carbon oil out and put her back on I do see a little oil in the intake pipes is this ok?

I will drive it hard to see if it starts surging again but is ok now.

As well I have a power steering or alternator whine how do I tell? I did the screw driver to ear trick but the sound is the same!!!

 

You will always have a little bit of oil in the pipes.
Is the steering fluid low?
Is the fluid bottle broke internally?

 

Good to here thought the Turbos were going!! I took her for a hard drive and 1 block from my house blew a coolant hose going to the heater core from the head!!!
As for the fluid I had just changed the HP power steering hose 1 week ago and all has been well. It sure sounds like a pump whine but the Alt has the same sound with the screw driver. I did empty the PS resivoir and add a can of the Lucas additive to see if the noise changed but no auditable sound change.

 

When you had the bottle empty was there a plastic piece laying in the bottom?

 

Never saw one it goes right down to the large drain tube on the bottom

 

There should be one attached to the top of the bottle where the return hose attaches at the bottle. Inside is where it attaches and goes to the bottom. If it falls if it sounds like it is low on fluid because it is airating the system.

 

There is a small shield there Thanks

 

Bad

Good

 

I just compared your great pics to mine and mine is the good one
