running sick

[redliner]

i went for a drive today and after about 3 minutes my r33 started to run sick, it is spluttering heaps and won't run smooth. so i went home and left the car, disconnected the battery and left it for 3 hours . my brother came over so i decided to show him the problem. everything seemed ok. he said maybe my fuel was low and picking up dirt. the fuel was low but not below empty. so we went to the shop to put some fuel in . on the way everything was fine. when we left the shop the problem started again.

my thoughts are. 1. fmic piping loose and air leaking

2. timing belt

3. spark plugs

4.there actually is dirt in the fuel line

5. some type of air/ vacuum line leaking.

if anyone can give me their thoughts it would be much appreciated.

Thanks

does it splutter when you accel hard? does the car systematically miss on idle?? if soo then best bet its the sparkies. id check your afm and give that a clean next and then check and change your fuel filter if it did pick up any dirt.

it runs a little rough on idle and splutters when accelerating hard. how do you check the airflow meter and or clean it.

also my leads and plugs are supposed to be doublr platinum and should last for over 100 000km's
