My Volvo revs up and down
They funny thing is that i got my volvo recently and was asking everyone about the reliability of the car car and now it revs up and down at idle.

any help is appriciated

RE: My Volvo revs up and down
Hey Tech, what about high end? My surges just barely enough to notice, but seems ok on cruise control. I notice it most when driving around 60, on flat smooth roads. Then it surges up then down, only about 100 rpm difference. But being a commercial pilot. I notice little changes like this. Maybe I am going crasy and expect to much.

RE: My Volvo revs up and down
The surge could be your foot. On cruise, there isnt a chance of accidental depression of the gas pedal causing a higher rev. With your foot on the pedal, every little bump will cause a slight change. The thing with S80's is the gas is very sensitive past about 50 degrees. (the angle, not the temperature.) Once depressed, the gas can be very reactive. At high speeds, unless its a T6 or a souped up S80, slight depression will not cause noticeable acceleration, but just a difference in RPM's.

RE: My Volvo revs up and down
Thanks everyone.. One more question. Sorry, just trying to learn the car.
When I punch it, power comes on strong, then at about 3200, surges down a bit, then around 4000 picks back up. It's not a solid pull like my other cars, but they are not turbo. Is this normal, the turbos just speeding up to catch up? I known in the Crossfire Merc compressor, the power increases steady until maxed. Reminds me of flying a jet. You hit the power, get a huge surge, starts moving, then when the speed catches up to the power, slows down a bit, then kicks you in the butt.
Thanks again. Just want to make sure nothing is wrong.
