I have a 2002 bugeye WRX, and when im cruising along the motorway at 60mph dead on, the check engine light comes onand stays on not flashing.
Mods at the moment are Power Engineering decat downpipe and the centre pipe is a decat or sports cat, im not too sure, but its deffo not standard, and a standard back box, it also has a ITG panel filter. Fuel wise its using V-Power.
It doesnt come on any other time other than at 60 mph. But!, it goes off after 24hrs or so! Does the ECU store it in its memory even though its gone off.? Any ideas why it could be coming on?
Thanks.
