Mechanic/elec needed

Hi there im looking for someone to have a look at my classic impreza next week sometime. Has check engine light on and flash codes are for boost control , idle control , and pressure control. Changed all items and problem still there, convinced its electrical problem . This problem has had me stumped for a while now and its time to get it sorted. could anyone take a look or recomend anyone to take a look next monday ish? thanks

Has the codes been cleared? Depends if the parts you have replaced them with are knackered aswel but its unlikely. I know Mark at Abbey Road Service station is shit hot at stuff like that.
