I have crower stage 2 street/strip cams non stock idle, i just rebuilt the whole motor . Now it will not idle. It will run but when i let off the gas it dies . I checked the timing over and over. I may need to check the valve lash since i installed the cams. Or with the crower cams do i have to make it idle higher But what do i do as far as the timing on obd2 , to get it in time i know i can't turn the dist. ????
