hiya i have a 1994 wrx wagon, its fairly modified with a hks mushroom filter, both decats and a stainless exhaust and a td05 turbo and a scoobysport chip. when i put my foot down the car runs fine and when i go around left corners but if im booting it around a island when i go to put my foot down the car just jerks violently till i let go off the accelerator but its fine when i press it again.
its doing my head in so any ideas would be appreciated

 

fuel surge ??

ask astraboy

 

Let me guess.... less than 1/4 of a tank?

 

Just what i was thinking

 

Either get a baffled fuel tank or swirl pot etc. Or keep a least half a tank of fuel in her at all times.

 

Saxo boy wasn't it? And anyway that was definitely lift off oversteeer not fuel surge

 

it evcen does it when i have half a tank, but its only when i turn right! do u guts think a walbro pump would help?and what will a swirl pot do??

 

id have a look at your coil packs mate aswell

 

I get a stutter every once in a while but mine is turning right then hard left. Bit odd but i'm going to get a catch can fitted with a new fuel pump in a while when i get it over to scoobyworld for a performance pack. Is anything logged in the ECU? Might be worth getting it plugged in at a specialist.

 

mine does this when at a 1/4 tank!! why do they do this??

 

Its called fuel surge, ALL classics do this, normally with around 1/4 of a tank of fuel.

I'm going to be be putting a swirlpot and lift pump into mine to combat this problem.
