EJ20 Intermittent Fast Idle

  1. Over the last year or so my 1998 EJ20 occasionally gets stuck in a fast idle mode. It’s annoying at junctions or when trying to drive slowly in traffic or across a campsite. Switching off and on again resets it and returns it to normal idle.

    I’m thinking IAC or temp sensor but it doesn’t explain why it always resets when turned off and on again. I will try cleaning/tightening the temp sensor connector in case it’s producing an intermittent signal, but has anyone else got any other ideas what may be causing this?
     
  2. Could be a neutral position switch issue,

  3. I hadn’t thought of that. I’ll have a fiddle with it but it happens whilst travelling in gear and then continues when I take it out of gear. When I take my foot off the accelerator (in gear) to slow down, the van just wants to run away. If I switch off and on again it returns to normal and you feel the normal engine retardation until whatever it is gets triggered again. It always starts and runs Ok when the engine is cold.
