VS 3.8 running rich please help

[lout]

lets wait for a code or several
and then see if we are on the right track
or 4-5 days of driving and then re-assess
hopefully this time it adjusts itself properly
in the meantime, try researching a scan tool that can read live data from a VS
maybe the vident i400? not sure if this will work on VS, autel md701 with holden software
i think long term it could be a worthwhile investment

Also I took the plenum off just incased there was anything unusual and found a **** load of oil in the intake

Check your PCV isn't blocked or stuffed.

That was filled with oil got it out cleaned it. How do you know if it's stuffed?

 

[lout]

most ecotec/alloytec get blocked
as you have oil in plenum
most likely not blocked
probably excess blowback on rings
probably never been cleaned before

So I swapped the plugs over and been driving all day. It hasn't thrown any codes yet but it has been shuddering bad when ever I hold a consistent speed at any speed.

any updates

Hey mate sorry for the late reply the car is running heap smoother ever since changing the injectors to genuine ones. I've run into a problem through when light throttle is applied (holding consistent speed) the car has a bad jerking vibration and its still taking off after the vibration. I feel like it's being caused by 2 issues one engine one suspension?

no fault codes?

 

[loch96]

None

sounds like on the way to being a reliable car
