no p codes detected by auto shop.. 3 years ago 80k miles a similar issue occurred and shop did acomplete tuneup.. when they tested the system nothing amiss was evident this time hoping to isolate issue without full tune up

Hello, Eddie here and I will do my best to help. it's been 80K miles since you had it tuned up last is that correct? And you haven't had the spark plugs replaced since that time?
