Can any body help ive got a vectra c 1.8 ls on a 52 plate and it had a problem with a blocked breather.
so i removed the throtle body to clear it only to end up with a constant tick over of around 1100 then increasing to 1500+ when warm.
Ive tightend the throtle body replaced the gasket added gasket sealer to remove any problem there. Ive also removed the egr valve as i had been advised that may solve it but it hasnt plus diagnostics has drawn a blank ???? please help
