right got an issue with my d16z6 hope you lads can help me.

I have done a search, but with no real luck.

Basically sometimes moving from stand still the car wont rev past 3k in any gear. if i hold it there for a while as it splutters it then frees up and continues to go up there the rev range. I notice this alot when ive jst started the car from cold and drive off but it can happen and does happen when the cars warmed up to.
somtimes this happens and sometimes it doesnt.
Over 3k..the car drives fine.
i do sometimes get code 43(fuel supply)

parts ive changed:

Spark plugs
spark plug leads(put on my oem ones)
fuel filter
Rotor arm
Fuel regulator
air filter
Lambda sensor x2
map sensor
Check my grounds and cleaned them
Check and tighted my throttle cable

Modifications:

skimmed head ported polished
aem cai
Dc sports manifold
apexi center section
tanabe rear
Custom De-cat

Any other suggestions?. as this problem is getting on my ****.

Cheers
