high idle problems caused by throttle switches!

Thanks, how do i set the MFA into diagnostic mode?

[Gambit]

with the ignition switced off, hold the MFA button in, then with the button still held in turn the ignition on, then off then start the car

always making sure you hold the button in till the car is started

then scroll thru the options on setting 2, there is a digital rev count somewhere there!

Anyone got a list of the readings a 16v golf should Be, the readings on there are for cabs and other models.

Thanks again

[Deefadog]

deefadog, 16v idle is between 950-1050rpm

if anything set your MFA into diagnostic mode and it will give you a digital display of the revs's - this is a lot more accurate than the clock

to set your idle

get the car upto running temp
turn engine off
disconnect the red wire coming from the coil (this turns the ISV off)
disconnect the engine breather at the airbox end
start the car
adjust the idle screw till its at 1000rpm
turn the car off again
re-connect the red wire
and thats your idle set

if it wont sit at a steady idle but flucuates up n down by +-50rpm then you need to get the CO level adjusted to 2%

Can you pelase show me a pic of the red wire and coild and which engine breather, is this the one that goes into the front of the engine?

and how do you adjust the CO, any links please

Thanks
