Idle problem under no load
Ok folks, here is one that is driving me bonkers. After R and R and hose job car runs great whenever it is under a load of any kind. However when everything is off and car is idling there is a sparatic miss in there. HC is too high as well per emission testing. Plugs and wires were replaced, as well as the coil harness (without ground) Sure sounds like ignition problem to me but don't know. Took it to Mazda and they checked the usual ,vacuum leaks ect. Computer not showing any codes...How do I nail this down...
