Title: poor idle when cold
Post by: byebye on 16 November 2010, 18:57
hiya, as above my 8v 1990 digi golf gti wont idle in the mornings without me sitting there holding it at around 1000 rpm, if i let go it just dies away, starts again ok...but it annoys me now its done it ever since I got it about 2 years ago. I was thinking maybe its the ISV? once warmed up its fine for the rest of the day  :smiley:
Any ideas? can these ISV be cleaned? checked? oh and the other day whilst under the bonnet I heard it buzzing dont think it normally does that ? :undecided:
Thanks guys

your isv is supposed to buzz thats normal  :smiley: check your vac hoses and rocker cover bung for splits will cause poor idle,check your blue temp sender, check and reset if neccasery your idle. have a read of rj"s tune up guide loads of good info and pointers

cheers, yeah i replaced my blue sender not so long ago, and the flying saucer bung last week. i'll have a look at the vac hoses when the rain stops if ever  :rolleyes: I'll also re-read rj's guide again  :wink:

i had the same problem recently after car was laid up for 2 years. it wouldn't idle at all. it was fine once up to temp but i had to hold the revs to get it warm

do rj's idle set up or as per haynes.  give the idle screw a good clean up to.

my idle screw was minging. once it was cleaned out it was spot on.
