It's not that lower or higher is better. It's whatever that particular set of heads should be operating at. You want to see all heads fairly close to each other in this regard. If you've got one that far higher or far lower reading than all the others it's probabaly bad.siamak5561 wrote:Jared wrote:siamak5561 wrote:Hi, is there command for check heads health?
