Hi I am new and I have a question and would appreciate any input you could give me. I have a 1998 s70 t5 and the engine cuts out every time I drive it. When I accelerate or I am just going down the road it will feel like the car pops out of gear but its then engine stalling out. Also whenver i am driving through town and get stuck at a traffic light and am waiting for longer then a minute or so the engine will turn off , Then when i go to start it , it fires up then dies immediatly then the second time i turn it over i pump the gas pedal and it tries to die but it then revs up and this process happens every time it stalls out .

Thanks for your help, Matt

 

You need to check the fuel pressure.If possible get a guage and leave it installed and when it dies see if you loose fuel pressure.

Do you have a check engine light on?

 

Hi The check engine light is on but it was hooked up to a Snap On scanner and it read that it was a secondary emissions leak or something and my dad is a mechanic but is not to familiar with volvos he has turned the light off twice but it keeps reappearing.
My fater had also just installed a new fuel filter about 3,000 miles ago the car has about 136,000 miles on it.

But i will try the fuel pressure test thanks for the input. Matt

 

It's your air mass meter. It regulates the amount of air and gas to your motor. They are about 300-350 to have replaced.

 

Hi Matt,

Our very recent edition to our garage of cars is a V70. Last Friday it died in the backside similar to your experience. The previous owner reported intermitent stalling problems over a two year period. The Volvo dealer replaced the airflow meter - twice in three months, and just about every other sensor. My newly found Volvo mechanic with 40 years experience said. " there are no fault codes" - "I feel that the fuel pump is stuffed - and the mileage would support the theory - you can do a pressure test on the fuel system but most likely the in tank pump will not play up at the time of testing - the on board computer will not record a fault with fuel pump". End result, the fuel pump was replaced - no more probs. Albeit I feel sorry for the previous owner.


Cheers ...... Nick
