Hi all im need to the forum. My name is Delvin i reside in Allentown pa. Im also trying to get BoostR attention as he is local to hook up his vida vice. Text me 610 200 8852 BoostR

I just bought a 04 volvo s60 with some electrical problem. Car starts and run. First problem i saw was the radiator fan turns on cold start and sound like a turbine. Got some code even after resetting for low voltage to the maf temp sensor, maf, fuel rail pressure, turbo, and boost senor. Reference code p0642. Ive tested voltage to fuel rail and it will read 5v then stop and come back on.

After warming up the car will stutter and lose power, start misfiring, transmission will go in anti-skid mode. Engine will finally shut down and wont start until a couple of minute then hard shift. Will do this everytime. Recently i got the reduce engine proformance.

I believe its the ecu. I have a matching spare gotten from the junk yard along with the cem. I know Ard can clone mine onto the new one. I dont think dealer are capable.
Any suggestion or help is appreciated.

Also if you can get BoostR in here maybe i can get more codes pulled that will be great. Thanks

doesnt sounds like an electrical problem. without scanning it I would say BPS and/or FPS, BPS will make the fan turn on full speed if its toast. Has your car had the fuel pump replaced like it probably should have? If you call volvo they can check to see if it was replaced during the recall.
