Hot Soak MisFire Rough Idle

Hi All,

After shutting the car off for 30 minutes after upon re-starting the engine feels like it is running on 3 cylinders. If I push the throttle to 3000 rpm and release the throttle it settles down and runs fine. It only does this after a 30 minute hot soak. Cold start is fine as is if it sits for 15 minutes or 3 hours. started to occur after the r/h valve cover gasket was replaced. Any ideas would be a big help.

Thanks,

Tom
