Hello I own a 2005 volvo XC90, I bought it during the summer and because I did not have a drivers license back then, it was siting there for at least a month and a half. When I finally got everything in order I noticed that there was something wrong with the engine. First off it needed the 90,000 mile service, so in the manual I read all the engine procedures the volvo service where going to do to the car and I did them, but that didnt solve the problem. The problem was that while driving on the highway, this happened in one second the car would lose power and decrease the velocity and then gained it back, again this would only take only one second. another was that while waiting for the light to turn green it would shake like one to two seconds and die on me, had to put back in parking and then restart the car and then drive. I think its really weird because I only use it to go to school and back and to try not to force the engine too much now when I am waiting at the stop light I would put on neutral so I dont use the engine too much, and in some rare occasions I would drive the car long distances and one out three times it would do the same about losing power and gained back in one sec. What do you guys think it is? I dont want to go to the volvo dealership and be like yes check everything and see how it goes and getting a huge bill and they found more errors than the one I am looking for.

 

You need to find an independant shop that knows how to work on Volvos. Do not go to the dealer unless you have lots of money to spend. These are good cars once you get them sorted out. Good luck.

 

is the check engine light coming on? if so step one is to get the codes scanned, which autozone will do for free or you can buy an OBD 2 scanner for $60 at any auto parts store.

 

i checked with autozone and the codes they gave me where P0193 and P0190.

 

codes are for fuel rail presure high/fuel pressure sensor malfunction. it may just need a new sensor.

 

i also read that it might be te fuel pump. how can i check wich one is it
