Car isa 2004 S60R 2.5T unmodified with an Automatic transmission.

Ok I am at a loss. My wifes car just recently started haveing some issues. I gota Service Engine light and pulled the code and it is a P0090 code. I also got a few codes for missfires in cyl.4 and 5. I checked the gas capand changed the fuel filter. Seemed to fix some of the issue not all though. When I get on it and demand more fuel she stutters now as if its not getting enough gas and timing is being cut when I demand more gas under boost or something. It will drive fine if i ease into the pedal to increase speed, but if i step on it to get her moving in and out of traffic she cuts hard and bucks.Has anyone ever had this issue before? Is it the fuel pump or fuel regulator on the fuel rail? Big difference in price between the two but just curious if anyone on here has run into this before or not.

Thanks guys

 

If you got a misfire code I would check the spark plugs and coils first.

 

IMPORTANT RECALL NOTICE
May 25, 2007
To all Volvo Retailers and Employees:
RE: Recall 181, certain model year(s) 2003-2004 S60/V70 Fuel Pressure Sensors
Volvo Cars of North America, LLC (Volvo) has notified the National Highway Traffic Safety
Administration and Transport Canada that we will perform a Voluntary Safety Recall to replace
the Fuel Pressure Sensor on certain model year 2003 and 2004 Volvo S60/V70 vehicles.
The fuel pressure sensor (FPS) located on the left side of the fuel rail, may at times transmit
incorrect signals regarding the fuel pressure to the Engine Control Module (ECM). If the signal is
outside of the pre-programmed allowable limits, a Diagnostic Trouble Code (DTC) may be set
and the Check Engine Light (CEL) will come on.
Engine misfire may occur during driving that in turn can reduce the engine torque, in the worst
case scenario the engine may stall without warning.

i cannot seem to post anything. This is starting ot **** me off [:@]

 

I will post more when Ican figure out why I cannot type more then a crappy sentence in here this is just too weird. 9 tries and all i get is that post above and maybe this one

 

yea go figure. Thanks for the info on that senor I will keep you all posted as to what I find. I am pretty sure it sfuel related, adn that senor was in my sites

 

The misfire codes went away after I reset them. I only get the P0090 now. I wsa hoping bad gas maybe. But that sensor was next to get replaced after the filter I did, then the fuel pump. Hope it goes well not wanting to do the pump.

 

Sorry for all the posts its the only way it will post my replies.

 

Thats for posting the recall first time I saw it. Forum acting up again techs working on it.

 

Well an update. I tapped the sensor on the rail and it seems to work fine now after I changed the filter, plugs, coils, and gas cap for seal. I guess it was bad gas. Here is something interesting though. I called my Volvo dealer to ask about the recall. He said it had been complied with previously. So they said even though the symptoms are the same I will have to pay for it to get fixed this time. At 90.00 per hour to trouble shoot they said they will find the problem (more then likely come to the same conclusion I did).
