engine is hard to start once the engine starts it misses for about 10 seconds than it runs normal, it doesn't matter how much fuel the tank has before fueling it. The engine runs great until we fuel up, does not miss at all,this happens every time we fuel up

    mis fire is usually an ignition issue. review when last tuned and get diagnostic run. maybe issue with pressure sensor. could reveal problem with fuel delivery also.

    Have EVAP system scanned, fuel entering system will flood engine momentairly and be hard to start/run rough then clear up until next fuel stop. Does it do any better if you dont fill up or doesn't matter the amount?
