Im just after suggestions and ideas as to whats causing my polo to idle so dodgy!
33% of the time it will idle just right at about 950rpm
33% of the time it will idle anywhere between 1k-2k and will drop back down to 950 or stall when i bring the clutch up slightly and the other 33% of the time it will stall or idle below 950rpm for a bit and then stall.
any ideas as to what could cause it do do this?sensors? isv? air flow meter? sticky cable?
is it worse at night (lights, stereo on etc) as i'd be testing the alternator.
and the timing too
my electrician mate tested the battery on tick over and with everything electrical on and he said it was good so im guessing timing.
mine was kind of the same....my altenator etc is all spot on and it was my timming being out by half a tooth which caused it (Y)
On that note. If a cylinder head is skimmed to near or Maximum then that would throw out the timing as well.
I`ll guess that Vernia Pulley`s are the way forward for more than just standard not being 100% accurate.
When i had my 1Ltr MK2 Loon some years ago and did the head gasket, GSF sold thicker head gaskets for
Heads that we`re skimmed but what to do with a G especially when people are using 6N metal head gaskets
can only be the vernia pulley.
How many of you use a proper or made Camshaft Locking tool.
I did a guys Cylinder head gasket a bit back and the head was skimmed a bit past Maximum as specified
by the manual and i used my cam locking tool to find the timing belt pulling the crank to one side of its
timing mark when tensioned. Nowt i could do but time it best we could.
What we need is a enthusiast 5 Axis CNC programmer who`s already made his wealth in life
to write the program and make us some heads at cost.
Oooh! The thought of it lol.

oem timing marks are at best shit. With my low miler with orig head gaskets it was still 1/4 tooth out!
