Hi

Thank you for that

what you are describing is a leaking injector

or faulty tip, use a heat gun , infrared , see what cylinder at the exhaust manifold is

lower temp., that would be the faulty injector

if it has been over 200K miles from a top end tune up

this will also cause this , injectors need to be replaced every 250K miles
