2001 Volvo s80 no throttle response
Hello,
I have 2001 volvo s80 2.9L non-turbo. Today, I was driving a car and suddenly it stopped on middle of the road. When I tried to turn the car on it would not turn on until I hold onto the gas pedal; if I don't hold onto the gas pedal it will not turn on at all. In addition, when I hit the gas the rpm remains at idle even though the gas pedal has been floored.
I do smell a strong scent of un burned fuel when the car is at idle. There is no check engine light on and there are no codes.
Few days ago, I did notice unusual fluctuation on my rpms. when I was cruising on highway, the rpm would suddenly go up and return normal where it was before.
Please help me. I can't seem to figure out what's going on with my car without any codes.
thanks in advance

Sounds like a bad or dirty MAF (Mass Air Flow) sensor. This is a small unit just behind the air filter as the air flows toward the engine. Try cleaning it first (search youtube for instructions). If the trouble persists, replace it. Autozone has two choices, around $100-150. Good luck, hope this fixes it.
