Can't accelerate over 4k rpm
 

Hello All

I am new to the forum and could really use some help before I lose my mind. I have searched and can similar problems to mine but not exact and the ones that are the same don't have conclusions. Anyway I have an 03 6 speed and have come across a strange issue, when driving I can't go above 4k rpm it almost feels like a fuel cut but in neutral in my driveway I can bounce it off the rev limiter if I wanted to. After some searching I immediately clean my maf and did an ecu reset as well as the relearns and now the car idles much smoother and throttle response is quicker till 4k rpm when it just stop accelerating no chance in speed or rpm it just stops but the engine stays running and to make matters worse I have no CEL's. Has anyone had this issue or can point me in the right direction.

Thanks in advance

Whats your mods? And does it have a osiris tune?

No mods bone stock

Running into the same issue after putting on my Nismo CAI, did you get this resolved?
