Post by: will_omegaCDX on 03 April 2009, 06:44:21
hello, i have a problem with the girlfriends corsa, its sound like it wants to stall on idle, and lights dim up and down when idling
a mechanic (suposedly) done head gasket not been right since

any ideas?, idle control valve?, timing out?, blocked breather?

i think so, its either in fusebox or when i used to have one it was in the center below the heater controls, does the paperclip test work on it??

just havin a dumb moment is here a sequence the same as the mig?, 12 12 12, or is it different??,
Title: Re: help with corsa

It'll be different as it's Pnnnn codes, so no start sequence code. No flashes = no codes stored. :y

[edit]Don't forget 10 flashes = 0 [/edit]

thats what i was thinking, when the head gasket was done the rocker cover wasnt cleaned out properly will clean out today and set timing up if its possible.
i suspected idle valve but thats ok.

That will be interesting as its a chain setup!

i relised that after i took the rocker cover off, how do i set it up?,

You set it by removing the timing cover, slackening the chain tension and moving it around a few teeth.

Seeing as you have dived in pulled the cam cover, check the timing.

Align the mark on the crank pulley with the one on the timing ase (its at about the 2.00 position).

Now check the camshafts are correct by looking at the slots in the end of them at the gearbox end....they should be in line
