busby 10 Posted March 20, 2012 I am new to the forum and new to owning a Corrado G60 , so in at the deep end! I do have a query that maybe someone could help or offer some advice on, I know it may be something discussed before but the symptoms are a little peculiar to me at least. Let me describe the problem: The starts well and idle normal, this will continue for a while and often not be a problem , however sometime I will come to a standstill , blip the throttle at it will stick at 1500 RPM before gradually dropping down to a what I would consider a high idle. I’ve taken the Idle Valve out and given it a good clean, and the throttle returns to a close. It’s as if the air regulation / fuel injectors aren’t functioning properly but on an intermittent basis ? A video is here although not great. http://youtu.be/xRmBW--kfCk Any help you can offer would be gratefully received. Thanks, Quote Share this post Link to post Share on other sites
busby 10 Posted March 20, 2012 after reading this: http://the-corrado.net/archive/index.php/t-23672.html? I'm not entirely convinced I was that thorough in cleaning the ISV, so I am going to have another go at the weekend! Will report back ! :) Thanks, Quote Share this post Link to post Share on other sites
Mike16v 10 Posted March 20, 2012 Busby, Just had the same problem with my 16v. I changed the coolant temperature sensor and that solved the problem on mine. Only cost £8! Quote Share this post Link to post Share on other sites
busby 10 Posted March 21, 2012 Thanks Mike16v, Managed to get one from GSF, it does seem to have helped but I can't be confident it's fixed the issue completely just yet, noticable the old one was stuck in with some silicone rather then just changing the 'o' ring , can I confirm that you just changed the Blue one, It appears there is another black one adjacent, maybe one for the guage and one for the ECU ?

slim_crx 0 Posted March 21, 2012 have pretty much the same problem, doesnt happen all the time but idle does stick and ive replaced the isv and cleaned it, so might have to try a temp sensor Quote Share this post Link to post Share on other sites
Mike16v 10 Posted March 22, 2012 Busby, The coolant temperature sensor on my engine had a white connector. It may have been blue originally but changed before I bought it. Mine is a 2.0 16v so I think yours may be different. I just have two sensors on the right side of the engine block, the one I changed with a two pin connector and a black with a single connection which I think if for the temperature guage on the dash. While we're on the subject of sensors, can anyone tell me where the oil temp sensor is on the 2.0 engine? Quote Share this post Link to post Share on other sites
