Hey yall, i have a 98 s70 t5 which has had a horrible misfire for 4 years now and i have only put on 2k miles after tons of parts replaced and misfire not resolving i finally found the issue! Fuel pressure regulator and fuel pressure damper! (Eninge codes only showed misfire codes) The regulator was full of fuel when i removed it and the damper on the fuel rail had the a very large fuel leak stain (clear coat stripped on one side of damper). Now the issue could be resolved if THE PARTS EXISTED! I have searched international for both fpd and fpr and have only found some no name fpr with correct 3.0 bar rating but after weeks for arivall and after install, the car wont even start! If any could please find a perferably new fpr and fpd that would be great, used it fine too! And yes i checked junkyards no luck
