Hey all. When I first bought my gvr4 and had it smoged, the mechanics said the timing was advanced and that he had to adjust it so it would pass smog so of course I said OK. I know I read somewhere that these cars (stock) run better with the timing advanced 5 degrees I believe. When I am at a light or stopped the idle drops to about 800 and the car has more vibration than I like. At 1000 RPM's it is perfect. Should I advance timing or raise the BISS to make RPM 1000 so it is smoother or am I totally off base. Just for the record car runs great this is only due to annoying shaking at 800 rpm.
Thanks as always guys.
