GT4THUG Posted August 2, 2011 Report Posted August 2, 2011 Just a Quick one, My 2.3 Ghia Galaxy (P reg) has started to over rev, to which looking thru the Haynes Manual it states that the idle is ECU set due to sensors, so i cannot re adjust... but it cant be driven safely at this and its getting annoying at the lights, so any ideas what to check first as the throttle cable is ok, and nothing seems to be disconnected but something is amis... just the spate of very hot weather has started this issue and as its a family vehicle i dont really want to be driving it in this condition , but dont want to start the tedious trial and error to get it rectified... thanks in advance Stu!

ggobin Posted August 3, 2011 Report Posted August 3, 2011 Has the temp gauge been working correctly? I had a similar issue and turned out to be a faulty temp sensor. Caused the Gal to fast idle. Quote
GT4THUG Posted August 3, 2011 Author Report Posted August 3, 2011 its been on and off since i have had the Galaxy , it runs low then occasionally works then runs low, ( and its nots the thermostat or anything ) just presumed its got a iffy guage / sensor and couldnt be motivated to fix as isnt a issue / important ... its only started as the ambient temp is hot.. so the temp is thinking its cold and running the fuel as if the chock is pulled out ? next question... if this is true... wheres the sensor and whats teh restistance to verify the sensor is dud and at what temp? thanks Quote
sparky Paul Posted August 3, 2011 Report Posted August 3, 2011 (edited) The temperature sensors are on the plastic thermostat housing at the end of the cylinder head, gearbox end - the one below is for the temperature gauge, and the one at the rear is for the ECU. Also make sure you check that the idle control valve hasn't stuck open, situated on the top of the inlet manifold. You can clean it out with carb cleaner, or a bit of petrol.

GT4THUG Posted August 3, 2011 Author Report Posted August 3, 2011 hi, the car just doesnt sit at the revs , its more noticeable when driven an gear change, it start to set the revs at where the throttle was ( then in idle) is the best description, but if i come to a junction and slow right down as to stall, its fine.. temp guage started to work and all symptoms stayed the same... ambient temp outside showing as 27 deg, and at norm temp Quote
