i have 2002 F150 5.4l that has been having misfire issues due to antifreeze in the banks have dried out banks and they end up filling back with antifreeze have had to do it for banks 5 and 7 so far anyone got any ideas why it might be doing this and what i could do to fix it

 

Wodda ya exactly mean by 'Filling up the banks'?

 

well the antifreeze fills up to where it cuses the truck to misfire so the spark plug and part of the coipack are wet and the water comes up the spark plug to up over the porcilan

 

Due to the bad spelling and lack of punctuation it makes the post hard to understand,but my guess would be possibly intake gasket.

 

The only way water can get that sides plug holes is the intake manifold. Its either busted or the gasket is bad. The intakes made out of plastic and they do fail..
