Idle speed control motor was faulty. Replaced with second-hand part, cleaned the MAF and my Echo goes like a little rocket again! Yippee!! Thanks everyone for your help - you saved me a lot of time and money - and hopefully this experience will help someone else in the future.

Thanks for your help - much appreciated. Injectors have already been checked - all fine. Pulled Idling Control Valve apart yesterday and cleaned with carby cleaner. Not sure if it is working OK. Someone else said I should feel vibration but I couldn't detect anything except a couple of air bubbles, as it was full of carby cleaner to detect movement. Car still runs very poorly. Do I need to clear the error message before I see a change?

The engine dash light of my 99 Toyota Echo came on a while ago. Toyota couldn't give me an answer without having to take the whole engine out $$$??? Another mechanic plugged it into a diagnostic machine and a message "Idle Error" appeared. No-one seems to know what this message means or the cause. The car has intermittent flat spots - sometimes runs pretty well and other times, I really have to drive it hard in 3rd gear to get it up highway hills. Can anyone offer any clues to the cause of this problem? Is it the computer playing-up, is it sensors? Do I have to renew every part one by one??
