Going up hills while holding the throttle at a constant pressure, the engine surges, then slows down, over and over and over until the top of the hill. Getting worse...I fear immanent failure soon. And Volvo only will replace if the car is under 10 years old. Which is ludicrous as ALL of these Volvo's will fail.
i throttle the gas and nothing happens..
I had the same problem and on my car the TPS fixed the problem. I found that on my 2001 xc v70 it is hard fixed to the throttle body. I went to a gunk yard and replaced the entire throttle body. That fixed my issue. Rather than spending $200 to $500 I spent $100.
The car will not rev past 2000 rpm in park. Running in limp mode. Will not go more than 24 mph on level road and slows to 8 mph when climbing a grade. Idle is is very rough.
No solution as of yet. Problem, When I accelerate fast to pass someone the car often shuts down, goes into limp-mode.

I've almost been killed by this, so now I do not pass anyone. The V70 XC now cannot be trusted. If I pass on a 2 lane highway and this happens I won't be able to control the car properly. maybe I may be able to pull back into my lane, but unfortunately nether the car coming at me or the car I just passed knows I've lost power.
Volvo better step up because so far no one seems to know what to do. One Volvo dealer told me it's the main control modual. 1270.00 + 2 hrs. labor + 260.00 reprogramming charge. Another Volvo dealer told me the mod. is fine but doesn't know why this is happening.
I need help with this before the car kills me.
Goes in and out of "Limp mode" ETS light comes on, car will not accelerate, it will after "pumping peddle" sometimes though. Does not always start but usually does after several tries. Very unreliable, only dare to drive it within a mile or so, I'm 65 this year and wanted this to be my last car, don't know about that.
It sure is a nice driving car and totally rust free, plenty of power before this started, I really like the thing. I don't know what it needs though. It has not been fixed yet, I live on a tight budget and not sure when this will get done.
Idle is rough ,won't go more than 25 mph, and the rpms go to about 2000
Throttle is sticking.
I got a used throttle body for $120. It is fixed for now but we will see for how long.
The previous owner had the module replaced and now it has gone bad again.

Currently less than 150k miles.

99 V70 XC
Car sometimes hard to start, takes a lot of cranking. Then when it does start, the engine won't go above idle. Have to shut down and restart. Then it runs as normal. No CEL.
Car would stall driving down road. Dealer fixed 1000.00
Car stalling going up hills and under heavy loads
The car will not stay on. It will run normal but stall after a few seconds of idle.
ETS Dash Light came on. have not yet fixed the issue.
Car hesitates and races.... Not yet fixed.
After several trips to Stadel Volvo replaced the Electronic Throttle Module. Total charges $618.11. One year later now i am having troouble with long shifting between gears, hard shifting, and the car will lunge forward with foot on the brake. Stay tuned.
ETS light comes on, power declines, acceleration unavailable (car goes about 30mph)- turn car off for about 10 minutes and it goes back to normal... until the next time it does it. dreading the repair cost :(
rpm drops from 9000 to 5000 and sometime stalls while in traffic.
