Engine & Gearbox / Re: High rpm when cold for 20 minutes,...?
Last post by philip -
Hi, well it's bizzare, tested the car this morning, idles at 1100 rpm for 15 minutes then goes back around 900. After leaving it to cool down an hour, it starts and idles way too low at +- 600 rpm for about 10 minutes. I think i'm going to leave it be now and stop fiddling as there is a big improvement in any case. Thank you all for all the help and especially the video you sent me that was so usefull to learn about the cab,... the old girl got 89000 miles, first owner from new. I wanted the GTI but couldn't afford it so got the last 1600 cc Driver without power stearing lol.

Thanks again,

Phil.

Well, I don't know how to explain this, may be the weather being so hot? I was up at 8 am down to the car all ready for the mission lol.
When i took off everything, i realised i didn't have the right tools to take of the waxstat. I then remembered that 20 years ago ( i got my golf from new ). I actually fiddled with the settings of the cab flap, sucking on the hostpipe turning that wheel,....So i thought, let's check the gap again that should be around 2.5 mm. It was way off ! No wonder i've been using over 12 liters of petrol per 100 K for years when it should be around 9.5 L max urban ( that's all i do ). So to make a long story short, i adjusted it as it should and then lightly gave a few hammer hits on the waxstat ( yes i know, pretty stupid ). In any case, put everything back, started the car, it idled at 1100 rpm, drove 5 minutes, when straight back to 850/900 rpm ? Must be a miracle ! But i will not know until tomorrow morning when it's stoned cold again if this did the trick ! Fingers crossed, Un-real !!!

yes sorry i did test the coolant hoses and they are getting hot. I was just about to ask if it was worth it to take it out and do the boiling water test in the hope of a miracle or improvement,...lol. I will do this over the weekend as at the moment weather here south east not the best,...If i remember well, I only have to take the air filter housing off to get easy access ? thanks again, fingers crossed as this problem just suddently started 6 months ago.
Yeah, just remove the airfilter and disconnect the hoses at the choke and the coolant pipe.  On the video I mention how many milimetres (cant remember) its supposed to stick out when its fully heated up.  I did my own one using this method.  Sadly a year later it started to leak.  Finding one in good condition is tricky.
