I have a 2004 v6 accord. When the car engine starts it starts rough. On occasion it will not start on the 1st attempt. This concerns me cause its my wifes car.

The dealership has mentioned that they can't find anything wrong (i guess no trouble codes so they have nothing to go off of).

I have seen some posts on the internet but no solutions. Any help would be appreciated. It only has 33,000 miles and has been doing it since about 26,000.

 

Have you put in afterparket spark plugs or anything?
Also if your talking about a long cranking time be sure to wait for the check engine light to go off after the key is turned to "on" before starting the car. That primes and pressurizes the fuel system, and will start the engine faster.
