Miss Between 2nd To 3rd Gear


Recommended Posts

Hey guys,

I got a RB20DET in my silvia i have fuel pump, FMIC 500hp fuel pump etc...all the mods to able to run 12psi with no drama's.

But i have a splutter / miss between gear change 2nd into 3rd then it goes fine only in that gear it does it.....and only on full throttle and its extremely annoying is bogs the car down....anyone got any idea's?

do you have a vent to atmosphere BOV? If so, then thats your problem. Its dumping air that the ECU thinks is going into the motor, and causing lots of fuel and no air to bog the car down, and pop between the gears from back fire.
