Rb26 - Hesitation At Around 2-3k Rpm?

[deek1182]

Hi All,

Been having this slight problem for a little while now and the garages out my way don't seem to have a clue! (No Skyline Specialists in Scotland! <_< ).

The problem is that when i put my foot down at low revs (say 1500 RPM) the car will start to pull but then hesitates at around 2-3k RPM (i can only describe it as if the fuel is cut off for a split second) but then it seems to pull through/past this "flat spot" and will rev smoothly till about 5k-5.5k RPM. Then the engine will slightly hesitate again but it isn't as harsh as before - its more like a stuttering as if the engine is being "strangled" i.e. not being fed a constant, continuous or even amount, of either air or fuel.

This is really annoying as when i purchased the car (begining of the year) it was great and had a decent amount of power

I really hope there is someone out there who has had this problem before and can help me locate the problem.

Thanks in advance for any help.

No replies, anyone have any idea at all? A stab in the dark theory? Heard of anything like this in previous posts?

Any help would be very VERY much appreciated!

replace and gap the plugs to .7mm, and or tune out the rich spot.

hmm. mine did exacly that when i had the wrong computer in it.(33gtr in 89 32gtr)

due to the titania o2 sensors in the early gtrs.

but it could be an airflow meter problem. if its only just started. see if you can gety a fault code of the ecu.

turn the dial all the way clockways and read the little led fashes.
