I have a 2002 accent with the 1.5 l and auto trans
When i start the car it will run but really ruff with next to no throttle response, and start chugging and coughing, what i have to do is shut the engine down and restart it any where from 1-4 times before it engine will run proper(close to proper anyway)

now i also want to add that the colder the weather the better it runs
and on hot days its getting a dieseling sound like it timing is to far advanced
everything else seems fine and as i am 3 1/2 hour from the dealer was wondering what you all thought of this
(i am thinkin that a sensor of some sort is to blame

btw i have down the spark plugs, air cleaner, timing belt and nothing has help me

help me

thanks in advance will check back regularly for any suggestions

very common fault on accent is h/t leads from the coils to the plugs. check for tracking(white marks on the rubber leads) hope this helps.
