Hi, thanks for writing in. This is a common problem associated with fuel/air delivery which is very commonly related to what is called a mass airflow sensor (https://www.yourmechanic.com/article/symptoms-of-a-bad-or-failing-mass-airflow-sensor). This monitors the flow of air intake into the throttle body as...

Hello. Thanks for writing in about your 2000 Porsche Boxster. Most of the time this is caused by the pilot bearing in the rear of the crankshaft. When it fails it will make this noise at these times. I usually...

Hi. It should be a fairly simple cause. I suggest checking your tires for uneven wear because that is the number one cause of pulling next to an alignment being out up specifications. So have the alignment checked (https://www.yourmechanic.com/article/how-to-know-if-you-need-a-wheel-alignment-by-robert-tomashek) as...

Hey there. This may be a sign of a dirty or failing mass air flow sensor (https://www.yourmechanic.com/services/mass-airflow-sensor-replacement). The mass air flow sensor is a unit in the intake system that monitors air intake as it is mixed with fuel prior...

It is possible that the noise and "no power" symptom you experience is the exhaust pressure in the turbocharger of your engine being released. In some cases, an excessively rich mixture of fumes in the exhaust is ignited causing a...

If all the tune-up maintenance...

My guess is that the overdrive relay or solenoid has failed. If either of these parts fail, your Volvo will not shift into overdrive. This is a very common problem on Volvos such as yours. A trained professional, such as...

There is a tensioner pulley (https://www.yourmechanic.com/services/drive-belt-tensioner-replacement) that keeps the correct amount of tension on your serpentine belt (https://www.yourmechanic.com/services/serpentine-drive-belt-replacement).

You need to have the codes scanned by a professional with a scan tool for the transmission computer. The codes may give you an indication if the sensor is not performing correctly. If it is not a sensor malfunctioning (like...
