on gas the car runs and drives fine. but flick it to petrol and when crusing along it's fine but accelerate from the lights or while driving and try to accelerate to gain speed and it splutters and carries on but then sorts itself out until you try to do it again.

car in question is a MPFI EB which has a 300kpa XR6 fuel pressure regulator and a brand new fuel pump about a week ago.

i reckon i'll try a fuel filter first, that hasn't been changed in 2 years. but you got any ideas?

sometimes it does it. sometimesit doesn't.
sometimes when you flatten it, it goes fine
sometimes when you flatten it, it splutters a bit then goes

I just put in a K&N Panel filter into my car and noticed surging at around the 2000 rev range up a hill.

I own a BA Falcon XT... Honestly, I'm just going to say it's probably the filter...
