Question about 2000 Volvo S70

2 Answers

Vehicle hesitates when you accelerate .

Have problems with acceleration. It doesn't happen all the time but when you need to accelerate the cars hesitate at times and they you have to press on the accelerater harder to speed up. The car runs real good most of the time ,but the hesitation comes and goes. Don't think it is a safety issue at this time but it seems to be getting worse. Could it be a sensor or a software problem?

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 driving.best of luck.

The problem was a bad throttle body that was covered by the warranty even with 88,000 miles and 8 being eight years old. Seems like the vender supplied defective throttle body for 1999 to 2002 years.
Check with your local Volvo dealers to get the work done. Should be no charge because it is a factory installed defective unit. I caught the problem before it became a hazard and cause injury or accident because the lack of power or the car stops operating completely while on the highway.

Temperature light and hesitation during acceleration.


You could have air in your coolant, causing this false reading. the hesitation could be related, if the air 'bubble' found its way to the coolant sensor.

2002 grand prix, changed the MAF due to code, tried a TPS from a shops recommendation. Also replaced fuel filter, car still hesitates and acts like it has a wrong fuel air mix. The hesitation happens...


It makes me wonder if the new MAF sensor did not fix the problem in that circuit? Were the codes cleared after replacing it? And engine light stays off? Only way to know is have them or someone check for new codes again. The codes direct you to a circuit malfunction. That's why a new sensor doesn't always fix the problem.
It may be something else, but one place to start is have the codes read again. If, as you say, may be an air fuel mixture, you could have your fuel pressure checked to see if it is up to specs. At least eliminate that possibility. Good luck.

As I'm driving along the road---vehicles hesitates


The symptoms your describing would indicate burnt valves to me. Do a compression test, it should tell you for sure. If any of your cylinders are off by about10% or more that will confirm it, you'll need a vavle job.

Santa fe studdering and won't accelerate right? RPM's jump and then steady with continuing studdering?


Engine performance problem causes are many. Try this first.
1. Disconnect the battery cables (both of them)
2. Touch/connect the postive and negative battery cables together for 30 seconds.
3. Reconnect the cables to the battery.
4. Drive vehicle to see if this solved the problem. Let me know what happens.
