So stupid me was mid/high revving up a huge steep hill to my house, my neighbors got stuck, and well I revv'd it in "Winter Mode" with the STC off all the way into my steeper driveway. I noticed that I was doing 50-60mph as i was going up the hill in 2nd/3rd Gear.

I hit the brake pedal and I slide backwards out of my drive way ROFL.., So I park itto the side and I snow blow my driveway.

I open the door of the car, start it, leave the door open and clean the snow off my car, I noticed the door was shaking rather noticeably and i quickly checked the inside of the car. To my finding the car was going "Vroom pause Vroom pause Vroom pause Vroom etc, until it finally stablilized off. The lights of the car were dimmining quite noticeably too.

Now everytime I start it (after it sits more than 15 minutes), it does the vroom pause thing.... There are no CEL lights on or messsages - felt like it was semi cutting out...

Could it have been the gas that I filled in the car? or was it cause I rev'd it hard up the hill? Also Volvo just re-cleaned my ECM too and I had the throttle body replaced already in warranty...

thanks In Advance

 

I would see if any codes show. There could still be some even though there is no messages.

 

so twice today, I let my foot off the gas, I was using the turbo, and i took my foot off 3/4 of the way.. The car decided to keep turboing on its own until 2nd gear. Has this happened to anyone, scared me both times... Im gonna get some codes tommorow, appreciate any and all feed back


no check engine lights or any messages up on the dash boad..

 

Maybe throttle body problem.

 

well my was replaced at 65k, and the new one was just cleaned at around 84k, Its possbleto have throttle body problems already??
