5.7 vortec idle is very erratic disconnected throttle position sensor and idle air control, idles and runs fine, replaced both no change. Only codes are random miss fire and vacuum leak at fuel tank, have checked entire vacuum system can not find a leak, replace fuel cap also. Any ideas email@example.com
