sakura n brothers :
MAS , AFM or anything la
located before the TB and after the Air Filter
both also doesnt and never comes when u buy a KNN air filter :)
KNN does not make electronics , they are making elements
even fuel filter elements
the thing sakura rounded in the picture is to place your stock sensor if not mistaken
if they sell sensors together , they have to make a sensor for every car on road , each sensor has a diffrent socket , summore , each sensor needs tuning , our ECU is not OBD-II to be tuned right. How to tune then ? if MAP sensors , yes u can fix Haltech , Motec , Microtech sensors , but of cos u use EMS to tune them up :) not just plug n play one..
MAP is manifold pressure . located at manifold , so its out of our topic here. But siemens protons is on MAP ?
Babygreddy : machi , i guess it could be ur throthle body (sakura said)
or Fuel problem (unker fred) said . Could be many things
When the thing happens , do u notice a Check Engine light on your car ?
if yes , the one of ur sensors are having problems ,
but i suspect its ur TB too , cos when change gear , u leave ur throthle off course , press clutch in , and press the pedal again top open ur throthle , main suspect i guess. If fuel filter or fuel problems u should have probs all the way :) not only when changing gear wor.
very very hard to say la, i had jerking problems at high rev after 7krpm
and then went diagnosed , it was my clogged fuel filter , my spark plugs cables also went dead together.
