im not sure what is happening i thought it was clutch slipping but it wouldnt be doing at same exact RPM every time.

heres what happends.

its a stock b16a3 motor with ITR intake manifold and 68mm throttle body idle is adjusted properly theres no bouncing idle issues.

when i start driving on cold engine i accelerate smoothly not smashing on it.

even accelerating normally i would feel a dip around 3000-4000 rpm every single time.

once the engine is warmed up a lil bit it goes away.

if i step harder it feels like the clutch is slipping thats what i thought first.

but it accelerates from idle to 3000 then dies out untill 4-4.5 rpm and gets power after that.

have no clue what it could be never had problem like that.

 

Measure the fuel pressure and test the FPR.

Also Ohm test the ECT sensor.

 

would absense of fast idle valve cause this problem?
the omni power TB has the fitv bypass.

also when i bought the car the thermostat was stuck open. now has a brand new honda oem thermostat. temps are normal.
AICV is also clean.


would a clogged fuel filter cause this?

i haven got a chance to check anything yet. will do in few days

 

why would it be doing it only when cold?
when warmed up the engine accelerates great with no problems.

 

Do some tests and post the results.
