i know its not a si but my old mans got a problem with his corsa-d hes a driving instructor and its a 57 done 115,000 miles so things are giving up, lately its picked up a odd issue of hunting on idle and no power, his mechanic took the throttle body off and cleaned it and it ran fine for a few hours little mishap but did run fine so hes been adivsed to buy a new one as there motorised and he thinks the motor has gone so causing the butterfly to flutter and suck in too much air on idle hes bought a new throttle body but he seems to think theres to many pipes coming off but we found out that one is obviously a fuel line and the other 2 are for some sort of water pipes but theres one mysterious one and i think its a vacuum pipe heres a pic anybody clear this up?
ps sorry about the sketchy paint jobbie lol
