Rough idle and hesitation, symptoms of a vacuum leak but seemingly normal fuel trims?
My car has had a very annoying hesitation / performance issue with a rough idle. It feels like bursts of vibrations when stopped (not a motor mount), almost like a vacuum leak. However my fuel trims are around 5-15% total fuel trim.
I have no check engine light.. I have also noticed sometimes when accelerating from a stop, the car has a very slightly delayed response and kind of jerks, and then accelerates.
Today I have been smelling a slight gasoline smell outside of my car after I turn it on.. any ideas? I m pretty lost.. thanks!
(Sorry, Y!A is screwed up and I have to post "Updates" with my info)...
One more thing, it's not a leaky injector (had them all checked and cleaned at a Honda dealer).
