what brand of filter? it sounds like maybe.... (if its a wet/oil soaked type air filter like K&N) that a bit of the oil is being sucked through the afm and messing with the readings. causing rough idle/missing etc..thats my 2cents anyway

If it was wet type, he'd still have the problerm after removing the filters, is sticks on there, if it was sucking that much in, he'd have to drown the filters in oil...sure he isnt that silly ?

Give the sensor in the AFM a clean with some CRC and reset your ECU.

Running a tune ?

Air leak somewhere perhaps?

Also. Straight 5-56 CRC lubricant isn't a great idea.. everything sticks to CRC. proper way to clean an airflow metre is to take it off the car, get CRC Mass Airflow Sensor cleaner. Clean it, let it dry, and put it back on.

Maybe try borrowing someones filters to put on? Doubt it's the filters though, but that will rule that out. If that doesn't work, maybe borrow their AFM's and see if that fixes it... Just eliminate possibilities

well cars are just weird, i changed the spark plugs over with new ones seems all good now. (old ones were black)

btw im running powerfc do i need to retune since i got MINES afms?

hmm its possible the ecu may need a retune. if it comes back start at the cheapest options and work your way up from there, as stated earlier borrowing parts is a cost effective way of eliminating potential causes.

    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
    • So, now all you need to do is connect the 2 or 3x 12v feeds into the unit to permanent 12v, ACC 12V and IGN 12V that you can find in the spot behind the stereo, and the earth, and then it will switch on with the car.
