Nice write up man i am doing mine this friday.

Just replaced the fpr and i still have a small loping sound, but not as bad as before i replaced it. Is this normal after installing a new fpr? Or could it be the CP3 going bad? Just got new injectors done and had the balance rates checked and the stealership said they were good and that i needed to replace my FPR, so i did. Has anyone ever installed a faulty FPR?
