Title: High idle problem when cold.
Post by: 40cent on February 21, 2009, 12:40:07 pm

Hi all got a idle problem with the polo which seemed to start when i fitted a jabbasport induction kit.

When the engine is cold i can start the engine and it idles around 1200rpm which is ok but when i start driving then come to a stop it revs at around 1800-2000rpm.

I can get the revs to drop to normal by putting it into gear with hand brake on and letting the clutch go slightly.
Ive fitted a replacement idle control valve but this didnt have any effect.

I seem to think i may be down to a timing issue but if anyone has any ideas on the what could be causing it then love to hear from you.

Cheers

Hi m8. the idle control valve was just a spare that i had which i cleaned up. I would imagine vw would still have stock of them but ive never enquired.
I pretty sure it is nessesary to take the inlet manifold off, i did anyway because i wanted to take a look at the breather at the same time but its simple enough to do.
