Re: Problem with throttle lag ..
There is one thousand and one problem that can be related to hesitation...
Fuel pump might be one of them but u have to tell us what model you r driving and which year is the car...
If u got a dirty idle valve, sticky throttle cable if it's one of the M52 car or a sticky throttle body flap, all will cause hesitation, and it might even be just down to changing spark plugs to resolve the problem....

Hi, sorry for the late reply ... I posted the thread few dozen yrs ago and no one replied.
Mine is a 320i E46. basically no mods whatsoever to the car at all .. I've called PML and they saw it could be due to a low fuel pressure ?
Another problem I forgot to highlight was in manual mode, either gears 1-3, while accelerating smoothly, my RPM will either drop slightly or stay put for a while before continuing increasing ..
In all, PML said they will need to do a computer diagnostic which may take 2 days including fixing..

Okie dokie...
But if u r a hands on person, u might wanna try the basic things like buying a carburettor cleaner and start spraying into the the air hose, after the MAF. The solution will clean up the carbon built up on places like the Idle valve, Throttle body, etc and that might just get rid of the problem.
If u have taken out a idle valve or a throttle body, u will know that carbon can build up on them, and this might just be the cause of the hesitation problem...
Simple job...
And oh.. u should know your car best, ask yourself when the the last time u change the fuel filter, the charcoal fuel for the fuel system, these are the main culprit for the fuel to drop pressure and in turn, causing the fuel pump to overwork....
The fuel filter and the charcoal cannister should be replaced every 60-80k..

haha I'm still trying to learn how to do those things you mentioned. So far I dare not touch the interior coz I'm afraid I can't put it back where it came from
Maybe I'll ask some friends who knows the technical aspects of this car and learn from them before I touch whats under the bonnet...
By the way my car is 1.5 yrs old with 16k mileage... I always like to keep things clean externior, interior and under the bonnet so that I drive with pride. haha
