Question about 2000 Volvo S70

1 Answer

Lack of acceleration

S70 automatic - Car doesn't have the power it had before. I practically have to almost floor it going up inclines. The engine is having to work alot harder than before. When I turn the car off the fan stays on now, never did that before. It began when it wouldn't go into 2nd gear right away, it sputtered before it would kick in.
Mechanic said on his plug-in machine it showed the Knock Sensor # 1 as being the problem. He cleaned them but the car is still doing everything I stated.
I feel like I'm going to burn the engine up in its' current situation.

Ok, i would advise to replace the knock sensor in this case. just cleaning them will not fix this issue. The sensor should be replaced. Secondly, this actually sounds lie, a malfunctioning PCM(aka ecm or ecu) at this point. I would have it checked asap.

your friend is on the right track, it does sound like it cvould be spark plugs but get the codes read as well, it is very common for coils to go out on those cars which will also give a misfire and lack of power.

Vehicle hesitates when you accelerate .

make sure you have the correct spark plugs(2)check the throttle position sensor on the car,as most people would be driving about with the throttle on the floor car feels fine.but as in normal driving anyone only uses the first half of the pedal and this is where most wear takes place and sometimes causes hesitation when of luck.
