Default 2004 S80 Idle stalling/RPM surge

Hello,

I am having an issue with my 04 S80 Turbo AWD 90k mi. I have the "Reduced Engine Performance" light on and it will occasionally stall out at a red light or stop sign. When I go back into drive, it rides fine. Also, sometimes when I start it, the RPMs will surge between 1000-2000

Has anyone ever had this problem? Could it be just a simple fix like changing the spark plugs?

Thanks!

So I had the spark plugs replaced and that didn't do the trick.....it hasn't stalled yet but sometimes when I am in Park it will rev up between 1000-2000.

I will keep this thread updated and hopefully somebody has had and corrected this issue

I hate to state the obvious because I don't know exactly what happens when these fail. But on either the serpentine belt or timing belt. Their are idler pulleys and a tensioner. I would try to troubleshoot there. Have you checked at-least the Serpentine belt for cracking at 90k?

I responded to another post you had. But it could be a PCV issue as well.

Took it to an independent Volvo mechanic and it's the timing belt. Also says that the Throttle Body needs replacement soon, and there are a few other things wrong with it.

$900+ for the belt and spark plug replacement

Really hoping the timing belt fixes the issues, and I don't have to keep pouring money that I don't have into a car that I just bought for $6,500

Lots of things like the spark plugs there are lots of video's on you tube how to do these for the Chasis volvo's.

That is what happened to me about 2-3 years ago. Got tired of pouring money into my car. So slowly but surely I started by replacing a door that wouldn't open from the inside. Moved onto to oil and filter changes. Then to spark plugs. Did brakes pads and rotors. I just replaced the engine mount and control arms/ball joints (can't believe I did that). Lots of these things aren't rocket science. I knew basically nothing about automobiles 2-3 years ago.

Just through reading forums like this. Watching some you tube video's. And investing in some tools knowing and knowing I could screw things up. But I would say I have saved myself a few thousand dollars and not been at the mercy of a mechanic trying telling me something I didn't know if it was legit or not because of my lack of knowledge.

I am not an expert on this by any means. But I always give my honest opinion as a car owner. Since you have Turbo, throttle body is something that can effect the PCV system. As to why personally when I bought my 02 S60 5 years ago I am thankful my Dad told me son you won't get a Turbo.

He had a 940 Turbo for years. I didn't realize it at the time I was only like 20 years old was thought turbo sounded cool etc. Thank god I didn't buy one.

With Turbo's you need to change the oil much more often; like every 3,000 miles I want to say. Overall it takes much much more maintenance. Knowing what I know now buying a used car and not knowing what to look for could be really bad.

If the engine is just running hot you might be able to buy and install body spacers. But the PCV issues seem to be common on neglected Turbo Volvo cars.

I am by no means trying to discourage anyone from owning these cars. You just have to do you due intelligence and know what you are talking about.

Personally had I known better I would not have bought a 02 s60 which of course ended up having the slipping transmission which cost me over $2k to have replaced with a salvaged unit. 25% of the original purchase price at the time.

Anything in life do your research and know what you are getting into.

Could be a PCV issue. Here is a great video explaining what the symptoms are. The more and more I read Turbos are more likely to have PCV issues.
