VS Ute stumbles after starting

[PorshadrivesaVS]

My ute has been having some troubles of late but the most tricky one to diagnose is why the engine stumbles and carries on for a while after starting , this usually continues for 20 min of normal driving or so, but when its wet or cold its much worse. The longest time it did it for in one go was about 200k (lismore to brissy!) if anyone has a clue why it would be doing this it'd be much appreicated !

check your spark plugs, leads.. could be coil pack..

cheked all those

Did the error codes show up anything?

 

[CHA53R]

check your earth wires, might be one loose... easy way to tell is run a thickish wire from your - (black) terminal on battery to somewhere out of the way on your engine take it for a drive and see how it goes if it works then theres the problem.. worth a try..

Id start with checking the codes,it only takes a minute or two and is easy to do.
