My r33 gtr has an annoying problem at random intervals it will splutter as if it were choking for fuel or air.The problem happens at low or high speeds doesn't matter what gear or whether it's on it's way to warming up to normal operating temp.Fellow owner asked if i had power fc or any other ecu upgrade as this can be a symptom of such upgrade but i don't have anything like that car is very close to standard.plz help i'm

check for boost leaks, passenger side intercooler pipe is a common culprit.
check your plugs too.

give your afms a clean...I had a bit of a stutter when mine started to fail..Cleaning helped but as they were a bit knackered the problem got worse..
