Hey Everyone,

So my T5 is acting up again. Its and Auto and under initial take off it lurches after a sec. RPM's dont really change much. Thats not the biggest issue though.

1st Recently When I go to start it in the morning it starts, studders, and stalls the 1st try. I know there is a PEM recall, but I dont live in those states and it has always been in non salted roads CO. It then starts the 2nd time always and doesnt happen again that day.

2nd Every few days or so when driving the RPM needle jumps, like a difference of 1000rpm or so, and the car shudders a bit. letting off the gas or turning off AC usually makes it stop.

3rd Under WOT there is def hesitation in the acceleration. Like its going rich and lean.

Does this sound like a fuel pressure sensor to anyone, or is this my PEM? If it is the PEM does anyone know about what that costs to repair. I know the FPS is about 90 from Tasca so I would rather do that and not do the PEM.

I run mid grade fuel always from shell. New plugs, air filter, coil packs, tcv, bps, cbv and vac lines. My boost stays constant and doesnt spike when this happens so I know its not that.

Sounds more like FPS than PEM to me.
If the PEM is actually bad it will be covered at no charge under extended warranty.

When I called the dealer in Denver they said that only Vehicles sold or registered in the certain states are covered under the extended warrenty, CO not being one of them. IF you know differently though I would love for that to be true. Thank You.

Well, I can't say for SURE as I'm not with Volvo but it sounds like they are describing the recall to you.

"MAKE/MODELS: MODEL/BUILD YEARS:
Volvo/S40 2004-2006
Volvo/V50 2004-2006
MANUFACTURER: Volvo Cars of N.A. LLC.
MFR'S REPORT DATE: January 18, 2008
NHTSA CAMPAIGN ID NUMBER: 08V033000 N/A
NHTSA ACTION NUMBER: N/A
COMPONENT: Fuel System, Gasoline: Delivery: Fuel Pump
POTENTIAL NUMBER OF UNITS AFFECTED: 23000
SUMMARY:
On certain vehicles sold in or currently registered in the states of Connecticut, Delaware, Illinois, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, West Virginia, Wisconsin, and The District of Columbia, reoccurring, long-term exposure to certain environmental conditions such as salty-wet conditions, it is possible for the Pump Electronic Module (PEM) to become corroded internally. This can cause a faulty signal to the fuel pump, resulting in low or no fuel pressure to the engine.
CONSEQUENCE:
If this occurs, the check engine light may illuminate. In some cases, the vehicle may fail to start or may stall, increasing the risk of a crash.
REMEDY:
Dealers will replace the PEM and install it in a new location to prevent corrosion. The manufacturer has not yet provided an owner notification schedule for this campaign. Owners may contact Volvo at 1-800-458-1552.

NOTES:
Volvo recall No. 190. Customers may also contact The National Highway Traffic Safety Administration's Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to http://www.safercar.gov.

There is also an extended warranty:

Retailer Technical Journal 20658
Extended Warranty:
191 Pump Electronic Module (PEM)
Date 03-06-2009
Reference: PMB 23-190 SMB 23-191
Note! If using a printed copy of this Retailer Technical Journal, first check for the latest online version.
AFFECTED VEHICLES:
Volvo/S40 2004-2006
Volvo/V50 2004-2006
DESCRIPTION:
Volvo has found that only after long-term, reoccurring exposure to certain environmental conditions (salty-wet conditions) it is possible for the Pump Electronic Module (PEM) to become corroded internally.
This may cause a faulty signal to the fuel pump, resulting in low or no fuel pressure to the engine. If this occurs, the Malfunction Indicator Lamp (MIL) may illuminate. In some cases, the vehicle may fail to start or may stall increasing the risk of a crash.
Once this condition is confirmed the corrective action will be to replace the PEM and install in a new location to prevent corrosion.

I have an S40 from AZ. Not covered by recall. I do have a letter from Volvo indicating coverage under the extended warranty. Perhaps a call to Volvo is in order.

That is very helpfull thank you. I think thats what they did. I will call them with that info now if replacing the FPS doesnt do it.
