how u clean afm? what do i exactly do to clean it?. what kind of product shud i use? shud i clean it with water?

yes factory turbo thats why i said everything stardard.

spec hks twin pod filter exhaust blitz intercooler twin blitz blow off 650cc fuel injector apexi power fc ecu 10psi everything factory standard! all that pulls 195kw not sure if that is tough or weak..

have found the best way to check for air leaks (vacuum leaks) is to squirt brakecleaner around any possible leakage areas. If there is a leak the idle will rise slightly. Start with the obvious things like pipework and rubber boots etc, try the split line on the bottom of the plenum chamber, Skylines are known to leak here, also check the intercooler for leaks and all pipework joints. To adjust the idle speed with the idle speed screw on the back of the plenum chamber you have to disconnect the Fast Idle Control Valve and the Idle Speed Control Valve and also the tps (good practice to check this fisrtly for <0.55 volts at fully closed. You can then set the base idle to around 750 rpm. Re connect everything and the ECU should hold the idle at 800 rpm. However the most likely cause of your problem is a blow off valve venting to atmosphere. This is because the ECU acceses the amount of air inducted and sets the injector duty cycle accordingly to maintain the correct air/fuel ratio. Once the BOV dumps this air the mixture becomes overly rich until the BOV closes and rpm etc equalise. My R33GTS25t did the same thing. Once I plumbed the BOV vent back to the turbo inlet (AKA stock) it was fine again. Finally the reason the Super FC doesn't use a map sensor is because Skylines don't have one, they just rely on the Mass Airflow Meter. This is also a common cause of many "Skyline Probs"

have u still got the stock blow off atm? what state ,suburb and mob number?

sound like alternator to me. if u replace a new battery and still have that problem best to bring ur car to machanic to check the alternator. if it was the alternator then u may need to recondition it.

try to research on coilpacks cuz i got a friend that drive a r34 gt and have similar problem. He found out it was his coilpack and spurg plug to replaces but im not sure how exactly how camery work maybe diff to skylines. im not garrentee ya it will fix that problems. Good luck!

It can be transmission oil leak or broken.
