Cheers for the reply..

I did have pools in the spark plug wells but thoroughly cleaned them out and cleaned the coil boots also. It did get rid of the bad misfires but still doesn't run very well.
I know I need to get the valve covers done so that's my next mission. I'm hoping that if they are leaking that bad, when fixed this will sort the hesitant acceleration and burbling.
I think valve cover leaks leave the ccv open or partially closed, not sure tho.
