Another misfire question

[jcweis1]

Hello all - new to forum today.

I have a 1996 explorer with 213,000 sohc.

I am thinking I have an intake gasket leak. I have to replace spark plugs every few months which corrects the misfire. I also have a slow coolant leak that is not visible and have small amount of steam out the exhaust. The codes are p0304, p0303, p0133, p0153, p1151 and p1152. the most common thing with most of these codes is intake air leak.

Any thoughts would be great!

I read somewhere that Barrs headgasket stop leak may work? Explorer is not worth the head replacement
