Right guys been having problems with my idle so today i messed around with the tps and replaced some vacuum lines took tmic piping off etc etc put all back together idling just under 1k now took it for a drive felt so much faster i was shocked how much quicker it felt... Heres the problem after 5 mins i have that stupid whistling sound come back on boost and then it hasn't got as much power and sometimes has a slight miss fire... I think maybe tps is completely knackerd but since that whistling im losing power would this be anything to do with TPS SENSOR???
