Rev bouncing on 01' s80
Could anyone please explain why the revs on a 01' s80 bounces whenever trying to park the car into place? They seem to only bounce when im trying to maneuver the car a very low speeds.
Since i have bought the car on 89,000kms (now currently on 93,000kms) i have not changed the spark plugs. Could the spark plugs be the cause of the problem? Or anything else? Please help.

you can go back and edit posts, so no need to double post,,,, basically it could be nothing , because then you are parking you are standing still almost (low speed) and turning the wheel requires more fluid pressure by the steering pump, thus more load, and higher rpm for the belt to spin the steering pump,
park you car and while standing turn the wheel left or right all the way, you will see this
or you have bad injectors or something dirty in the fuel, i duno , intermittent problems are the hardest to diagnose

Oh i see, lol i didn't notice that, thanks for that, that may be the problem i still have to service the car so it can work to it's full potential, i have just recently got the car so i will get to it as soon as i have the time. But thanks for the help 'nicolaselias' and 'andrei3333'

I disagree, I almost drove though my garage door
before I beleived my wife about this problem.
It has to do with a thin film resistoer being worn
and sending erratic ignals to the ECM
Even if the dealer worked on it once there is no
saying it was done "permanantly".
The initial repair involves leaning it and altering
some parametrs in the ecu. If that doesn't work then
they'll replace the unit.
again do a search on Matts Volvo site
it is an ongoing problem with all
early s80's

try Matts Volvo Forum , or something like that, they seem a bit
more knowledgable than this site. When ours went there was no other indication,
no check engine light etc, As it gets worse the rpms drifted up and down at idle
and a slight touch of the pedal might lauch the car. Sound familiar?

Volvo dealer can check your vin# to see if it's had the recall re-programming done. I have a 2000 and had a surge at idle problem, as well as rpm drop at idle too. Cleaned my ETM/throttle body and it runs like a dream. Was all carboned up so the butterfly was restricting airflow. When the computer sensed that, it would surge. Scared the hell out of me a few times as it lurched forward in drive!
