Idle Drops
Ok, been having some voltage problems ever since I put the underdrive and overdrive pulleys on. So I finally put an under drive pulley on the alt, and now when it is in park the idle is at 700rpm then when I put it in gear it almost stalls out, idle drops to 400rpm then rises back up. A mild cam is the only internal mods with headers, LS6 intake and some other small stuff. 99 Z28
