2004 Nissan Pathfinder: Stalls while idling or driving-Check Engine light on. But-runs great sounds amazing & My Mechanic did basic diagnostics-checked ground etc....Everything looks great Sounds great .From reading it sounds like a Bad Cam Sensor[known Nissan problem] What do I say to dealership to cut to chase & not rack up huge bill on same diagnostics tests and trying to diagnose this tricky but well known issue? Would love a little advice as to what to say to them. I have auto experience but am NOT a mechanic and dont try to be but I do know quite a bit from 3 years in car biz w/Toyota. Thanks!!!
