Yankee Ruin X Posted July 1, 2005 Share Posted July 1, 2005 Hi i'm new to all this and I've only had my supra for about 3 weeks and everything was going well until the other day. I took my induction kit off and cleaned it because it looked dirty and well it was caked in stuff so I got it all clean and put it back on. Now when I start the supra up from cold it ticks over at about 1500 until it warms up then it goes down to about 700. Is this normal its just I'm sure it was never that high before I took the kit off usually just under 1000 from cold. What do you guys thinks up with it any help would be greatly appreicated. It a N/A if that makes any difference. Cheers dudes Quote Link to comment Share on other sites More sharing options...
Guest Daniel H Posted July 1, 2005 Share Posted July 1, 2005 I too am in exactly the same situation mate. I have an N/a too k the induction off and it ticks over at 1500 to start then drops. I think its perfectly normal, as I dont know about you but mine only hovers at 1500 for a minute or so. Taking the induction off shouldnt make to much difference as long as its seated back exactly the same way you took it off i.e there are no small gaps letting air escape, that would mess up your ecu I think. You could make sure its seated right then do an ecu reset? Or I may be talking crap at least thats what I did in my FTO when it was having troubles with idling. Anyway hope this helps.

Yankee Ruin X Posted July 1, 2005 Author Share Posted July 1, 2005 Yeah thats what mine does it only does it for about a min then starts to drop. I thought maybe cause the induction kit is now clean and believe there was alot of muck in it that maybe cause the air is getting in easier that it might need an ecu reset. I thought the ecu adjusted itself automatically on these anyway. How do you do an ecu reset by the way. Like I say I'm a complete newb Quote Link to comment Share on other sites More sharing options...
Guest chiefvinso Posted July 1, 2005 Share Posted July 1, 2005 I have not had the experience of a supra start up from cold yet but I would have thought that as with any car it woud idle above the 1000 rpm range from cold. I think it will vary from car to car depending on mods, age. Don't know if 1500 is acceptable but it isnt too bad as it drops once warm and as its getting warmer does it gradually decrease? How long is it there for? Sorry I cant be much help. Quote Link to comment Share on other sites More sharing options...
Pete Posted July 1, 2005 Share Posted July 1, 2005 Totally normal for many cars. ECU is in cold start mode. Usually noticably worse in the winter and goes on for longer. If it doesn't settle down after a few minutes it could be a bad sensor. Quote Link to comment Share on other sites More sharing options...
Guest Daniel H Posted July 1, 2005 Share Posted July 1, 2005 Mine went up to 2000 odd the other day and then back down pretty quick, as far as I know its normal but then again ive only had my car about two weeks. ECU reset is usually disconnect the + terminal on the battery for a good 20 -30 mins but I wouldnt do that until someone with a bit more know how than little old me comes along.

Digsy Posted July 1, 2005 Share Posted July 1, 2005 Its normal for NAs to idle high on cold start. Quote Link to comment Share on other sites More sharing options...
Yankee Ruin X Posted July 1, 2005 Author Share Posted July 1, 2005 Yeah It decreases as its warming up its just it was never like that until I took the induction kit off and cleaned it so I was just worried I might have messed such a simple task up. Maybe it swallowed a spanner or something mind you I think the results of the supe swallowing a spanner might be abit more damaging than ticking over abit more than normal Quote Link to comment Share on other sites More sharing options...
Guest Daniel H Posted July 1, 2005 Share Posted July 1, 2005 Dont worry in my old car I drove around for about 6 weeks with a 12mm spanner in the engine....was only when I went to use it again I realised where I had left it...uh oh!!! LOL A friend of mine drives East german cars around and stores 2 stroke oil in his engine bay!! Is a bit weird though how I did the exact same thing as you the other day..induction of fand cleaned back on with higher revs....small world..

Yankee Ruin X Posted July 1, 2005 Author Share Posted July 1, 2005 Yeah tell me about it atleast its good to know that someone else has done the same thing and I'm not on my own. Cheers for you help anyway guys Quote Link to comment Share on other sites More sharing options...
mikeyb10supra Posted July 1, 2005 Share Posted July 1, 2005 20-30 secs will be fine to reset ECU mate ......is it auto or manual.....the autos seem to idle higher than manuals for some reason.......if it happens and does not settle down, check your throttle cable etc Quote Link to comment Share on other sites More sharing options...

It a N/A if that makes any difference. Cheers dudes Don't worry, it's normal. Just the ECU doing what a manual choke did in years gone by - revving higher until the engines warmed up. If you 'hot start' it (like in the petrol station) you'll probably see it rev that high then drop off immediately as the temperature readings take effect. You could also try it without the AC running, as this causes it to run a few hundred extra revs. Chris Quote Link to comment Share on other sites More sharing options...
Yankee Ruin X Posted July 1, 2005 Author Share Posted July 1, 2005 It a manual mate. Starting a new thread now see if you can spot it. Quote Link to comment Share on other sites More sharing options...
trebor69 Posted December 26, 2009 Share Posted December 26, 2009 I've been wondering about mine , its an n/a and has always shot up to 2 thousand revs on start up from cold and settles at 700 after about 5 mins , its fine when its warm . Surely its not good for the engine to rev so high before the oil has a chance to get up there ? Quote Link to comment Share on other sites More sharing options...
