Hello everyone I think my map is going bad I'm new to diagnosing with hptuners but my truck has been surging and stalling at idle speed and this is what I see on my logger looks like my kpa goes to 100kpa without warning truck surges then goes back to idle comfort zone 40 or so then I give it some pedal the map will start reading normal for a short period then does it again about three key cycles later .https://www.dropbox.com/s/fpxf0oecye...14554.jpg?dl=0
