Greystoke Posted July 20, 2006 Share Posted July 20, 2006 The Choke is not coming on when the car is cold. Revs stay at about 600 Is there a sensor or something I can check. Link to comment Share on other sites More sharing options...
Jake Posted July 20, 2006 Share Posted July 20, 2006 Supras have a choke? Link to comment Share on other sites More sharing options...
TRD3000GT Posted July 20, 2006 Share Posted July 20, 2006 Automatic choke .. Im 99% sure Dunno how to fix it though.. Link to comment Share on other sites More sharing options...
Jake Posted July 20, 2006 Share Posted July 20, 2006 A choke is only found on carburetors, innit? Not on fuel injection systems? Anyway, 600rpm sounds like a pretty good idle to me. Every Supra I've had idled around 650rpm just fine Link to comment Share on other sites More sharing options...

Jezz Posted July 20, 2006 Share Posted July 20, 2006 Supras have a cold start valve not a choke? Link to comment Share on other sites More sharing options...

Jezz Posted July 20, 2006 Share Posted July 20, 2006 Tell tarzan where it is then Jeremy. I dunno! I just assumed that fuel injection cars have a cold start valve rather than a choke. Somewhere on the plenum? Link to comment Share on other sites More sharing options...
Matt Harwood Posted July 20, 2006 Share Posted July 20, 2006 The Idle Air Control Valve is bolted on the engine side of the intake, right at the back. It has two water feeds and one breather pipe, (or filter), and a plug with about 6 wires going to it. Generally most Supras tend to idle higher when on cold start. ~900 rpm.

bondango Posted July 20, 2006 Share Posted July 20, 2006 Has this problem only happened recently?? due to this warm weather the cold start wouldnt be activated on start up as it operates via the coolant temp AFAIK Link to comment Share on other sites More sharing options...
Greystoke Posted July 20, 2006 Author Share Posted July 20, 2006 It has only started doing this in the last 2 days. The car would be started around 8am so the coolant wouldnt be warm. Link to comment Share on other sites More sharing options...
Jake Posted July 20, 2006 Share Posted July 20, 2006 Are we talking about a TT here? (Sigs are good you know;)) Apart from it idling at 600rpm is there another problem? If it idles OK at 600rpm I would be quite happy. Have you tried an ECU reset? Or maybe done one recently? Link to comment Share on other sites More sharing options...
andrew7 Posted July 20, 2006 Share Posted July 20, 2006 Try cleaning the contacts on your temp sensor ((near the thermostat) They tend to get bad connections.. Or maybe it's the temp sensor itself.. Link to comment Share on other sites More sharing options...
