Hi,
I had a bad hpfp according to live data so I replaced the diaphragms inside and now I am reading around 730psi idle and 1000-1300 psi under load. However when I rev the car up about 3.5 it will get to 4K then stumble, shudder then if I keep pumping the throttle it sounds similar to running it with the throttle body bare of the air intake pipe like that low tone noise. Then if you let go quickly the engine will shake like crazy. Restart the car then it’s fine.
Could this be anything to do with swirl flaps?
Im not pulling any codes from the engine module at this time either
