hunting idle when cold - Page 5

Gouldy · 09-12-10, 08:47 PM

what is the csv mate?? i know the warm up reg is getting live, the cold start injector is working, the isv is doing nothing,

so i need to get the isv working regardless, just trying to find out where the two wires from the isv go to really, then carry on working from there

just had a quick hour on the car looking at the wiring and trying to get the wires "a bit more tidy"

and noticed that in the fuse box i dont have 2 relays, could you KV guys check to see if your running them at all??

it looks like underneath there are wires going to them, but no relays are present, also does anyone know what they would be for??

also noticed that this yellow wire is off and looks like it should go somewhere too, its connected at the rear end of the fuse box

really want this car sorted soon as i will be going back to work in march and want to have a drive before i go back

Don't worry about things u don't have to worry about

One bridge should be in AT relay place, other probably in place of fog lights relay.
I can't remember what was yellow/black, but should be ignition for for some optional equipment like electrical windows etc.
If u are worrying about one connector, what u would do with car like by B3, where is at least 20 unused connectors in dash wiring harness?
