ardandy 0 Posted November 3, 2007 Report Share Posted November 3, 2007 Ok, just replaced the temp sensor and that sorted that problem out! Woohoo!Unfortunately an old problem has re-appeared.On start up it revs at about 1,100rpm to 1,200 rpm, when it gets warm it then decides to idle at 250rpm! It doesn't cut out but its close!I had the Idle (something) valve replaced a few months back albeit with a used one.Am I being unlucky or could another sensor be out which would cause this?It also seems to overfuel when cold, whiteish smoke (although not loads) and a petroley smell.Any thoughts?

amazak 3 Posted November 3, 2007 Report Share Posted November 3, 2007 Did you fit a new sensor or used? I had the same problem on a polo, it turned out to be the temp sender on the thermostat. Link to post Share on other sites
ardandy 0 Posted November 3, 2007 Author Report Share Posted November 3, 2007 It was a new sensor and it cured the cutting out problem.Just wondering if its a MAF/Lambda type thing? Link to post Share on other sites
amazak 3 Posted November 3, 2007 Report Share Posted November 3, 2007 ardandy,Sorry did not read the original post correctly. What do you mean by overfueling?, are you saying this because of the petrol smell?? I guess we are nearing winter so most cars have whitish smoke around now.....mine does. Also the fumes from my exhaust does smell a bit rich but I would not put it down as "overfueling" becuase it is not that strong also I have a performance exhaust, not sure if that makes a difference.When last was the spark plugs replaced ? Could be a faulty plug hence unburnt fuel? Link to post Share on other sites
