Alright guys, I filled up tonight and it seems to have worked. I did a couple things differently though. First thing was that I didn't fill up entirely, due to having no money
. So perhaps that might have done something, probably not though. Secondly, the last time I filled up it was raining, I know that CAI have some problems with water but this is a SRI so I don't know if that would affect my situation. I can't recall if it rained the first time my problem occurred so maybe it was just a coincidence that it was raining. But to conclude, my problem was solved by just reseting my ECU (undoing the battery for about 10 minutes). Next time I refuel I'll try and fill all the way up and see if that was a factor. But for now the problem has ceased, thank you everyone for the advice, much appreciated.
