Bugger! SWMBO's new Yaris has the MIL lamp lit up. She says it came on on the way home from the dealer, but she ignored it, thinking it would go away! I'm not going to repeat what I said to that!
Anyway, does any kind soul know a method of reading the fault codes without a FCR, before we have to go traipsing back to Derby? I haven't driven it yet (apparently it drives OK), but the idle speed seems a little low. Sticky IAC valve, perhaps?
