Mad Matt Posted March 18, 2009 Share Posted March 18, 2009 Gents, I got a new problem last week, this time engine-related.My day (in the car).In the morning I start the car with no problem and drive to work.After a hard day of work my car idle's like shit.The revs sit around 400-600 and it shakes horribly.There is also a lot of smoke coming from the exhaust and it smells like half burned fuel or something, car also responds crap on the gas, with a little bit of gas, it shakes and doesn't run smoothly.Next morning or later in the evening all problems are gone and the car runs perfectly with no smoke what so ever.I brought the car to the dealer and they replaced the sparkplugs (which was overdue anyway) and it ran smoothly as always, till just now and it was hopeless again.Does anybody have an idea what the problem could be.Was thinking about selling the car because I need something bigger, but i can't sell it like this...

WallaceGlanza Posted March 18, 2009 Share Posted March 18, 2009 You could try changing the engine temp sensor as it sounds like it doesnt like running hot.Other things to check are the condition of the spark plugs to show signs of overfuelling and also the map sensor as if its not wroking or reading incorrectly it can cause runing problems.

Mad Matt Posted March 18, 2009 Author Share Posted March 18, 2009 temp sensor sounds like a reasonable option as the temp almost never comes close to halfway. Quote Link to post Share on other sites
WallaceGlanza Posted March 18, 2009 Share Posted March 18, 2009 temp sensor sounds like a reasonable option as the temp almost never comes close to halfway.That could also be due to your thermostat being stuck open. Quote Link to post Share on other sites
Mad Matt Posted March 19, 2009 Author Share Posted March 19, 2009 well just got back from the dealer, checked it and came up with the conclusion that the "choke-housing" is fucked.(not sure if its called choke in English, its what keeps the engine at a certain revcount when the engine is cold)If they hit it with a screwdriver, the revs bounce like crazy.Anyone know where I can get one? (preferable cheap) ;)And if the n/a version is the same as the turbo one? Quote Link to post Share on other sites
WallaceGlanza Posted March 19, 2009 Share Posted March 19, 2009 "choke housing" I guess is the same as the automatic choke, is it the bit at the end of the inlet manifold? Thats the idle control valve which I think does the cold idle, it can be taken off and cleaned which usually is all it needs. Quote Link to post Share on other sites

WallaceGlanza Posted March 19, 2009 Share Posted March 19, 2009 Its the thing on the left side of the inlet mani with the electrical plug in it, if you unplug that plug then the idle will drop a bit. Quote Link to post Share on other sites

Kennedy Posted March 19, 2009 Share Posted March 19, 2009 ^^top right of the inlet mani mate.Theres a black circular piece of rubber..take that out n you will see a screw ;)i think it was clockwise to turn idle down n anti-clockwise to turn it up ;) Quote Link to post Share on other sites

If you unplug the electrical connector the idle will drop as I mentioned this can cause an erratic idle if its gets to dirty. Quote Link to post Share on other sites
