warm up idle

[d_jay1]

the idle on my new '90 scala injection goes a bit mad when it's started from cold. it rises and dips about every second and stalls without your foot on the gas. I'm presuming this is related to the cold start valve but this is my first injection model, so i'm in need of what to look at!

someone seems to have bypassed a valve to the rear of the engine with an electrical connector to another connector/solanoid at the front via a long wire. will take pics and post when i get a chance.

thanks mate, i just found that too!

i reckon its the WUR to be honest, as i don't have any other problems (as yet!).

any idea where i can get one from? GSF don't do them by the look of it, and ebay only have ones from the US.

I bought the 2 spares I have on ebay - if you cant find any there im sure a couple of the gti forums will have people selling them or theres always people breaking their cars..
