I have a my 95 impreza was driving and boosting fine but then when on boost gets to 4500 rpm and car seems to hold back on boost,so i done a ecu reset as it through up a cel 33 which is speed sensor but speedo has never worked due to broken cable and never had this problem before,car was boosting fine over 4500 rpm for about 5 minutes and then through up cel again 33 speed sensor again.if it is boost solonoid were is it located and what does it look like and can it be cleaned and with what. is there any way of testing the soloniod .the car is standard apart from a dump valve and exhaust and boost gauge,the car is a import.it never had problem with boost before any help asap welcome,and can u buy boost soloniod new.or can u by pass em lol.

 

just fount a live wire of amp in boot so was wondering if wire is shorting out will that cause boost soloniod to not work properly.
