Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
It been running weird for a while so I change fuel pump and pretty well all engine sensors to try find the prob but I really notice it after I put a shift kit in the trans as soon as I drove after that it started to stall on idle but run fine above idle and the idle was really erratic then On idle all of a sudden trac light would com on the dash with out me turning it off and I had no control over it and now it won’t even crank over and now my obd plug not working can’t earth plug 5/6What did u do prior to this happing paint us a picture..
