hey guys i have a 1990 honda accord lx with a 92 jdm H22a swap..
i changed the spark plugs.. wires.. distributer cap and rotor and it still lags.
i dont know if its a problem with the fuel map.. or maybe the e.c.u needs to be re-chipped.
maybe the fuel filter is bad but i dont think it would do that
the problem is that when the car is completely warmed up and after i get on it and hit vtec it will lag.. seems that maybe its just the timing but nobody can find the mark on the flywheel.
I NEED HEELLPP PLEASEE

The timing marks on the the harmonic balencer, a restricted fuel filter can cause this, do a complete induction and engine decarbonning, SeaFoam through the intake will do it.
