Can someone help me out here? I've done the paper test on the VRIS and they are not opening. The car bogs when normal take off but when I floor it there's power and no bogging but does not run as fast as it did the year before. I know because I took it to the track and the time was half a second slower. Is it the VRIS solenoids or the EGR? Any feedback would be greatly appreciated. Thanks!
