jerky low speed g60

Recommended Posts

my g60 gets a bit jumpy/jerky when driving at very slight throttle openings....for instance when trawling along at 30 with your foot just on the pedal

 

its seems to be related to the actual on/off from a slight opening....if i close the throttle at say 3k and let it slow down its fine

 

i asked this a while back and was told get a new cable,well its no better....and the idle switch works and is ajusted nice

 

and my mounts are new/good

 

any ideas??

Could be a faulty ISV... Do a search on here for ISV and you'll find loads of info on cleaning and checking 'em... 8)

 

Also, check your Vacuum hoses... Could be you may have a slight leak...

What's your fuel consumption like ??

 

With the engine at idle speed, disconnect the blue temp sensor wiring plug - does this make the idle lumpy ??

 

When was the fuel filter last changed ??

 

Is the problem worse in wet weather ??

blue temp thingy disc....not really lumpy, maybe changes the idle a bit

 

fuel filter done within 7-8 k

 

same any weather

have you checked the idle switch on the back of the throttle body ? might be worth checking continunity between brown/? wire to pin 6 on the ecu.
