DC2R Laggin

ok, i got a better explanation.
when the TEG is on low revs, the throttle butterfly or whatever its called it is called, is closed or open very slightly.
so therefor hardly any air is passing through there to feed the cylinders.
when the engine is going spastic, at 8000rpm, then its got a constant fast flow of air going through the throttle body.
NOWWWWWWW
to get from zero to max flow will obviously take a lil, if not very lil bit of time for the air to accelerate. That very little bit of time is what i think is LAG that you experience.
when you floor the gas, the cpu gives full fuel, but the air has gotto play catchup and accelerate to meet the demands of the fuel.
This is just my oppinion, based on my limmited mechanical and physics knowledge.
please correct me if i'm wrong, cos i like to learnas i like to learn :D:D:D

Bludger: The ECU will not give full fuel because it knows hows how many RPM the motor is spinning at, the Throttle Position Sensor and Manifold Air Pressure(MAP)Sensor will be giving the ECU signals in contradiction to your explanation.

The air does not 'accelerate' that fast, as the engine can only use so much air as the RPM rises. This obviously does take time... The MAP sensor allows the ECU to determine the volume of air being ingested by the motor based on the RPM of the motor.

The problem here was actually spark plugs and distributor, causing insufficient combustion of the air:fuel mix and basically making it a pig to drive. Essentially, it was running at <75% of its normal power output. Having a 'dead' cylinder actually reduces engine power by more than 25% as the engine has to exert energy to rotate a non firing piston.

If the motor gave full fuel just above idle, the motor would either not accelerate or stall.

Check all your sensor...is all working properly?

soooo, when my car "HESITATES" you're sugesting that i have something wrong with the spark (plugs, leads, dizzy, coil, batterry)?
Why does it only "HESITATE" at low RPM [<2500RPM]

This was exactly the problem, only distributor actually. Just open up your distributor and see if its fried or not.

Bludger: The ECU is FULLY capable of removing ANY hesitation from your engine as long as the engine is serviced and maintained(except for the dip in power at VTEC switch point)

I suggest you check your spark plugs, leads and dizzy but it could be anything.
