Rough when starting
 

I just had my fuel pump replaced at dealer on my 96 accord DL. The next morning when I starting the car it ran rough. I started the car several times, each start was very rough. The motor felt and sounded like it was dieseling, but with the ignition on. Than at the next try, it started up normally, a smooth idle and good sound. All day the car started normally. This has happened seveal times now, but only in the morning at the 1st start of the day. Any ideas?

Check your Idle Air Valve..
