jonathantennantbtinternet Posted May 5, 2017 Share Posted May 5, 2017 Have a '96 K series 1.6 Supersport that appears to run rich at idle The engine runs an original ECU, but has a head by Minister Racing - different cams, gas flowed head, uprated gasket and verniers. On the move it seems to be okay but when at idle it seems to be running rich. Spark plugs get sooted up quickly but are dry. Any ideas.....

jonathantennantbtinternet Posted May 5, 2017 Author Share Posted May 5, 2017 Think the cam timing has been checked ? Link to comment Share on other sites More sharing options...
revilla Posted May 5, 2017 Share Posted May 5, 2017 Coolant temperature sensor OK? If that's gone high resistance the ECU would think the engine was cold. Link to comment Share on other sites More sharing options...
jonathantennantbtinternet Posted May 5, 2017 Author Share Posted May 5, 2017 Unsure if it's been checked yet. Any idea what the resistance should be ? Link to comment Share on other sites More sharing options...
