Hi guys my 96 wrx has developed a problem. When coming on boost it cuts all power under heavy acceleration, just read codes and it's showing MAF sensor, crank sensor, idle control sensor and speed sensor! Was wondering if one of these sensors could cause all the faults as it's very unlikely all to be gone at same time and what one would you recomend to stop the car losing its power? Many thanks for any help

 

clear codes and see what comes back ?
