I wonderif anyone can help me , done an ecu fault codecheck on my95 wrx , the codes ive got back are 23=mass air flow sensor, 24=idle air control solenoid ,31=throttle position sensor and 44= wastegate duty solenoid , is there anything i can do to repair these faults or would i need new , any info appreciated thanx ,ive actually managed to clear them but havent drove car very hard since so they havent come back yet , or is there a possibiltiy ive cleared them and they wont come back, at all

 

They're probably old codes, so don't worry too much.
Keep your eye out for them coming back though!
