[Johno82]

Hey all, My 2005 VZ SS runs a little rough at idle and when i take it for a rap it some times stalls when breaking WTF?? its auto as well but it now has got the SVS alarm up ( Service vehical soon ) not the dervice reminder mind you. I've used my ODB2 and found no codes....any help would be great

Regards

Start with the basics like throttle body ,give it a clean . Than move to spark plugs or leads . Just a process of elimination

Should be codes if SVS has displayed. Try another scan tool.
