SOURCE: 2000 VW Jetta V5 accelerator/idling problem

these cars are fitted with a fly by wire accelerator pedal that is controlled electronically by the cars computer it is possible that there is a computer problem or the throttle body ( air intake system )or accelerator pedal is playing up.
it is highly possible that the car is doing exactly what you say it is i recommend you take it back to VW and demand that they take a proper look at it you might have to leve it with them for a couple of days and get a service advisor to drive it home so as they can see the problem ocure.
regardles the cars computer should of thrown a code declaring a fault in the system witch should give the tecs some were to start looking.

good luck with this problem if you have any outher questions let me no

SOURCE: Golf 4. comfortline 1.6. 2002 model.

the hunting can be caused by leaks in the intake system.
these can usually be heard with the engine running & bonnet open and a hissing sound especially when blipping the throttle.
also check the crankcase breather hoses which go from the oil filler cap to just behind the coil pack, they are prone to cracking.
re. the acceleration, ther could be a problem with the throttle control unit.this is the unit the accellerator cable is connected to.
a scan with a diagnostic tool will tell you if that is the problem.

SOURCE: check engine light p0411 code what must i do

this has to do with your secondary air injection incorrect flow. start looking for a vacuum leak especially around the air duct from the mass air flow sensor to the throttle body.

Fuel injection


The most common causes for "idle hunt" is a dirty throttle body or faulty idle air control valve. The computer uses the control valve to regulate idle speed.
There could also be a vac leak somewhere.

Honda Accord 1991 idles high then low


)The fact that thge engine idle fluctuates when it is cold indicates that the Fast Idle THermo Valve is out of adjustment.
This valve is located ot the front of the intake manifold on the driver's side just below the accelerator cable. To adjust it, wait until the engine is cold (best to do it first thing in the morning).
Remove the two screws holding the cover on and start the engine. There is a brass needle sticking up through a plastic ring that has two slots in it. With the engine idle fluctuating, use a thin flat blade screwdriver to SLOWLY turn the ring CLOCKWISE
until the idle stabilizes. Once done. put the cover back on withg the two screws and you should be done.
