Hi all new to this site it looks good, just a question i got a wrx classic in 1st thing in morning its hard to get the car started once started its fine and starts all the time then but the check engine light comes on, im gathering its a sensor somewhere,

Is there a way in checking to see what fault code comes up by bridging 2 connections together of the engine bay, as i had a gt4 before and thats what you had to do, if you know what i mean if i made sense cheers guys
