Vectra C Z22SE Lumpy Idle

[Stu08]

Hi guys,

I have had my CTS and lambda sensor replaced recently due to poor warm starting issues. When the car is cold it fires up first time no issues. If I have driven it (say to refuel), left it 5 minutes and try to start it again it really struggles and fires up weakly.

Today I have now noticed it is hunting on idle. Any ideas?

Cheers for any help.

air leaks on inlet manifold ?

I'm looking to get a 2.4 manifold soon. Will see if it kills two birds with one stone. Extra power and problem solved! Going to blank the EGR, see if that fixes the problem.

There's no egr on the 2.4 in the first place m8 so you'd have to blank it even if you hadn't planned to.
