are there any sites that tell you how to time up a 93 wrx(marks on the pulley etc etc)also are there any engine ecu codes ....my engine light flashes..once..once...three timees....113 seems to be the answer....help a desperate guy..regards nigel

 

Firstly I don;t believe you can adjust the timing as the ecu does it all despite the marks on the pulley and front of the engine which confused me..

Best site for ECU codes is ECU Codes

Code you describe sounds like 23 which is MAF sensor and it on the air intake.

thanks for advice jolly green monster turned out to be crank shaft sensor so did temp fix...thanks

 

Cleaning the crank and cam sensors is a good idea..

They are suppose to work through the dirt that accumalates on them but have found they work better when they get older if they are clean.
