hi guys have bein searching the forum for past few days to try solve the problem,

when driving the car off boost at a steady rpm the car kind of hesitates or holds back for a second then normal then back to hesitating does this on an off, and on tick over rpm drops low and a vibrationm can be felt in the cabin,

car is a sti ver5 type r, with apexi plugs, hks bov other than the standard,
i cleaned the valve on top of the throtle body full of black carbon( how should this work just in case it faulty) and map sensor wit eletrode cleaner.

thanks.

Take a look at the maf sensor, it may need cleaning.

 

look at the sensor looks new almost but looking further i noticed oil coming from the bottom of the pipe between the i/c and throtle body, is this normal

thanks

Phil
