Hed Honcho

I have a 2002 sti PPP. The other day I took the car out in the morning, no issues and returned home. About an hour later I went to start the car again and it started but sounded like it was on 3 cylinders and really rough. The engine management light came on straight away. I started the car again and it started fine but the light remained on. Car drove fine with no issues.

I left it over night and started it yesterday, this time on the button and no EML which has stayed off...

I had spoken to API and am going over there on Tuesday to get the car checked.

Seems really strange how the light has gone back off? Anyone else had similar?
