Hey there. Have a vt commodore that is running real ruff at idle but seems fine as soon as I start driving. It has over heated once but have put seal up in and tested head s and all good. Has been running rough for a long time now. Are plugs and leads a good thing to try. Also there is no vaccum leaks.
have the same problem?
