What part should be relaced to stop my car from accelerating and surging?
What is your question?
The first thing that happened was that it wouldn't start on the first turn. Then it stalled at a red light - then, I was driving 45 but the car was trying to go 70 - it was like cruise control was on - I had no control of the car. The breaks felt weak. At the same time, my temperature guage was going up to almost the red area and then dropping to the bottom then back up to middle ( normal) - all this was happening within seconds/minutes of each other. The car would calm down and the temp gauge would be normal then, it would accelerate and the guage would react - this went on for 10 miles before I could just park it. The shop replaced the idle air control valve and said it was fixed. I drove it off the lot and with 27 miles it acted the very same way. They have been test driving it for the past week trying to make it 'act up' again but it hasn't done it for them. I will not drive this car until I know the proper part/sensor/module has been replaced! It is too scary and I will have an accident or hit the car in front of me. Can you please help!

you really need to find a local Volvo specialty shop that can diagnose this problem. you may have more than one issue. these cars are very hard to diagnose and you should
look for the shop with a parking lot full of Volvo's....no
Chevy's or Honda's; just Volvo's. intermittent problems like this can be difficult to identify and they take time and money.
Thank you so much for your answer. I took it to the Volvo dealer last Thursday and guess what...there are no codes in my computer and they can't get it to 'act up' so they are test driving it just like the other place!! Yes, I agree this is tricky but wouldn't you think the Volvo dealer would have some idea of what could be the problem.
