Dave Posted April 18, 2017 Author Share Posted April 18, 2017 For motorway driving it's a fuel saver 4K revs in D 3k revs in OD it's a no brainer Link to comment Share on other sites More sharing options...
Dave Posted May 6, 2017 Author Share Posted May 6, 2017 Could it be a sensor or relay ? Link to comment Share on other sites More sharing options...

Chris Wilson Posted May 8, 2017 Share Posted May 8, 2017 I would check the auto box oil level, correctly, engine running in Park, first. Link to comment Share on other sites More sharing options...

Thanks Chris will check the levels tonite ,I've just swapped the TPS ,and it's running a little high on tickover ,would that make a difference ? Haven't set it properly will have to do that also .

Chris Wilson Posted May 8, 2017 Share Posted May 8, 2017 The TPS setting is critical to many aspects of the engine and gear box control strategies. I hope you haven't twiddled any throttle stop screws as well??? You MUST reset the TPS sensor STRICTLY following the workshop manual. if you've twiddled throttle stop screws without a reference to return precisely to, you are in a pickle... The TPS being set wrong can and will affect the auto box control... Link to comment Share on other sites More sharing options...

Ok set the TPS and revs are now steady at 650-700,put the original back on which I marked up before I took it off ,haven't touched the throttle stop screws, I read it's a no no .just got to take out for a test .
