jerky wrx
 

hi everyone some help or advice would be much appreciated i just bought a 2001 wrx its been a disability car so only done 36k with fsh anyway the problem is if i give it some off the lights its hesitant when i change gear then it goes and if i just labour the engine and try and bring the boost in its pretty gutless just wondering if there is anything i could have a look at to sort this problem out
