its vti 2002 prosmatic
following things already done
engine several times tuned by honda 3s
new air filter ,plugs and throttle changed and serviced
gear swapped with an other vti got same problem
ecu changed with vti same response.
Accelerator wire changed with new one
generator serviced
engine is in perfect condition no problem at all
all gauges are showing normal warmup and stand alone rpm before moving in good
the only thing i understand is it happens mostly when engine is cold or early morning
when throttle serviced it drive like new car for a day then again this problem starts less on warmed up car.
Should i change the throttle again????
