pointless on a stock ecu....
and a stock b18a
his is different its vtec so u can get alot of aftermarket aids for tuning. ie. vafcs etc.
but mine does that sometimes its a little jerky first off try taking the throttle body off and cleaning it... because theres a sender on the throttle body that can get clogged up and let this happen.. try that first and the other obvious things maybe a new fuel filter aswell...
what happens is the pcv from the valve cover obviously lets the oil vapour go straight into the intake manifold then burnt up by the engine... because of this it clogs shit up and thats what happens... happens aswell sometimes when u get engine hunting...
