Jay85 Posted March 9, 2014 Posted March 9, 2014 Hi guys, I only ever seem to post if something's wrong 😁 Since I bought the GT (aka project puddle jumper) the idle has been really high, on cold it idles at 1800-2000 rpm, warm she idles at 1200-1400! I've swapped out the idle speed control valve, no change, any ideas?? Cheers Quote
mech5107 Posted March 10, 2014 Posted March 10, 2014 Put it in diagnostic mode and adjust idle using the screw on the throttle body. Should be around 800rpm. Quote
Jay85 Posted March 10, 2014 Author Posted March 10, 2014 The idle screw is screwed all the way in and fitting the new valve hasn't helped, does it need to be in diagnostic mode when this is done? If so how do I put it in diagnostic mode?? Quote
Jay85 Posted March 10, 2014 Author Posted March 10, 2014 How do I check/test that mike?? Where is it located?? Cheers Quote
Jay85 Posted March 10, 2014 Author Posted March 10, 2014 (edited) And I can check for vacuume leak with easy start?? Or is there another way?? Edited March 10, 2014 by Jay85 Quote
Jay85 Posted March 10, 2014 Author Posted March 10, 2014 Ok, so I pulled off the tmic and stuck my finger over the lil hole by the tb butterfly and the engine cut out! Adjusted the idle screw up and repeated and she idled perfect!! Guessing I need to replace the tb?? Quote
Mad Mike EP82 Posted March 11, 2014 Posted March 11, 2014 Cold start thermostat is located under the tb It has two coolant lines and two vac. 1 coolant line from back of engine where water pump main pipe is and the other should go into the engine below tb if this is not connected properly it will causd high idle.

Jay85 Posted March 12, 2014 Author Posted March 12, 2014 Checked all the pipes and they are all good!! Guess it's a throttle body replacement to try now!! Unless there's any other suggestions?? Quote

Sorry for spam but is this the same for glanza? Quote
Jay85 Posted March 13, 2014 Author Posted March 13, 2014 Think so mate, the engines are identical Quote
Jay85 Posted March 13, 2014 Author Posted March 13, 2014 Sooo... Changed the tb, and the idle is perfect!!! Quote
