Hi all,
I have a re-occuring problem with my R33. When under full throttle, when it reaches 4500rpm the revs almost come to a halt and the engine feels like it's really struggling.
So far, it has been currently un-diagnosed as to what it is.
I have changed the AFM, coil packs, CAS, fuel pump and had a HKS twin power unit installed incase of ignition breakdown, all to no avail.
the ECU reads 55 in diagnostic which is no fault.
I'm starting to go out of my mind, anyone else encountered the same or similar problem??
any help would be greatly appreciated!
