vz holden commodore svz rough idle issue

[Craig64]

Hi I have 2007 vz holden commodore svz ute alloy tec high output . Timing chain not long been done , used genuine holden timing chain kit ,
had this issue before timing chain ,,, On first start Car run smooth . then reachs temp & auto choke cuts out , then it runs a bit rough . like it has a cam in it,,,but it hasn't . But when you drive it , there is no lose of power & goes great ..I was told it loses pressure down 1 side , but come good when drive it ..he said it might be a air leak under manifold or pinched hose ,, have pulled manifold of put new gaskets & still does the same thing ,,any ideas please

Could be spark plugs, coil or injector. Try and book it up to a scan tool

Hi

Could be one of the camshaft position actuator solenoid problem maybe, they change cams position

check the evap solenoid isn't sticking open when the engine temp increases.
