right thought i would update you all about my problem,,, after a google search i found 2 possible things that could cause my power steering issue 1 was tps sensor on throttle body the second was alternator pulley as this operates on a clutch ?????? .. Well any way i decided the easiest thing to change was the tps sensor on the throttle body so went scrap yard (turned out to be not so easy and straight forward ha ha ) i took the hole throttle body including the tps sensor and fitted today took about an an hour and a half for me to swap throttle bodies but problem still was there (dam) was not happy .... this pointed the the other possible problem the alternator clutch pulley and after adding up costs as i cant change this my self (aint got a clue ha ha ) thought just scrap it!!!! but luckily i decided to start un plugging sensors and trying if it made a difference so i unplugged the maf sensor car did not like that ha ha ha then i unplugged the one nearest the throttle body on air intake pipe nothing happened was still the same . then i unplugged what i later found thanks to haynes manual was the mass idle meter and done no revving problems does not go mad when i turn the steering wheel this has got to be my problem soon as i plug it back in my galaxy goes mad especially when sturning the steering wheel
