Hi Guys

 

Havnt used the Z for a few days, but when I did yesterday, I noticed something a bit strange that I dont think has ever happened before. When I started the car, all was fine but was idling at 2000rpm. I thought it was just because it was cold, but 30miles later, whenever I stopped at a junction etc, it was still idling at 2000rpm. I went to a car park, looked under the bonnet, and nothing was glaringly oviouse. Throttle position was fine, water temp sensor connectors all seemed to be fine. So I switched the car off, then back on and it idled normally at 900ish rpm for the rest of the 70mile journey?

 

Any ideas? Is a valve or sensor sticking?

 

I know a lot of people go on about these ecu codes, and checking sensors, but can anyone give advic, or know where to get advice on how to read these and what they mean?

 

Many Thanks

 

Karl
