I have a B16A swapped EF. The odd time I'm getting abit of a sputter while the engine is under load, only in the low-mid range, if its sputtering and I romp on it the throttle response is crappy but it ripps up into the high revs without a problem. Could my timing be off or maybe old spark plugs? The car feels slower then when I first swapped it, the only addition since then has a been VAFC install.
Any ideas? What should I set the timing too and how do I set it properly with a light.
