Spark Plug 'reading' question
Hey gang,
I'm still working on a hesitation issue and have a question. Upon reading my spark plugs, the inner 2 cyl are running leaner than the outer 2. With or without connecting the O2 sensor. The outer 2 plugs are reading richer. I just pulled and flushed the injectors and replaced seals and hats, but the hesitation is still there. I marked and switched injectors, moving the inner 2 to the outer just to see if the problem goes with the injectors. If not , any ideas what would cause the 2 inner to run leaner?
If I connect the O2 sensor then its apparent that the 2 inner cyl are running too lean, which is probably why I have the hesitation.

well there are some flow differences in the stock intake manifold, but w/ a stock head i doubt they'd manifest themselves (as the head's the limiting factor i a stock setup)...
