2008 Suzuki Swift 1.5VVTi. The south African Suzuki dealerships dont know how to resolve the throttle seemingly getting stuck under choke conditions only. In the mornings while the vehicle is still under choke conditions the throttle would seem to get stuck. Once the vehicle warms up she runs great and no throttle problems at all. The condition is getting worse and worse and due to its intermittent nature there is no fault codes or anything to capture.
The fault is also difficult to replicate as you only get the condition when driving under choke conditions.
When I leave the vehicle idling in the motorhome to operating temperature I dont get the issue.
Any advice would be greatly appreciated.
The Ecu then sends commands to the fueling and ignition systems according. If the sensor is faulty and thus sends incorrect , or no info to the ecu as above, the fuel and air mixture will be incorrect and thus do as you describe resulting in poor running and no start situations...
If you remember the old auto and manual choke systems...it works like that , only electronically. If and when the choke was in the wrong position for the temp of the engine, the engine either wouldn't start or coughed and spluttered... exactly the same, temp related too..
So, without the aid of plug in diagnostics at the moment and the results thereof - its well worth renewing that sensor. Its usually located on the inlet thermostat housing , inlet manifold or thereabouts depending on model and has a two wires pin connector going to it.
Always buy one from a dealer / genuine unit. If you are unsure as to its position - ask the parts dept; when you are in there, to show you on the screen where it is located ....
