its just a bit of fun, and they never seem to throw anything up on the yaris ECU's and they are very tempermental. also Ed, an OT question but a question none the less, My k12 CG10 DE idles intermittently when cold at 2000 rpm, and sometimes stalls, i know the starter motor is on its way out, and its getting a good service on friday, but is there anything else that i should be looking for?
