Engine Cutting Off

[johnwd]

hi wondering if anyone has had this kind of problem on there r33 gts-t my revs started going up and down alot just out the blue when idle i thought it must be the afm i have arranged to sort one out in 2 weeks but ive found another problem now and a again when driving my mph drops even if my foots to the floor total loss of power than can come back on and off again and acts like its going to stall as it gets to low mph engine cuts off as if the key is in mid position lights come on ect no power steering could this be something with the afm or is it a fuel pump issue thanks for your time

Sounds like your afm is dying

mine just died recently and it was like you described

it just cuts out voluntarily and surges.

I had this problem recently with the idle hunting and then dying turned out to be the battery wasnt that great and when the alarm was set it emptied it abit too much.That tripped the computer too much and wrecked it. but airflow meter is a definate possibility. if you know someone with a skyline switch the airflow meter over.

Try checking your fuel filter, leads and spark plugs. The fuel pump could also be the cause - however problems with the fuel pump tend to be less frequent in regards to the symptoms you have described.

took the afm out last night and cleaned it up as much as i could the mesh was black with muck so did that too it seemed to help alot there was alot less popping on the exhaust so i guess that not as much fuel is going through im going to attempt to re solder some of the pins and see if that brings it back to life , but so far looks like it is the afm due to how i havent had the problem since i cleaned it
