Hi All,

I’m new to the forum and to owning a Nissan. I just got my wife a 60plate 1.6 petrol Qashqai and have noticed when the engine is started from cold the revs sit at 1500-2000rpm for a minute or 2 then drop down to normal. I know this isn’t correct for a non turbo car and was wondering if anyone else has had or come across this issue?

Hi....welcome to the Club

It is normal for the revs to rise to a certain level after start up and drop within a short time once the Lambda sensor goes closed loop.
However, it should only really rise to approx 1200rpm maximum.

You can calibration settings for the throttle housing via a scan tool quite easily and this should return it to normal rpm

Also, worth checking for any vacuum leaks in and around the intake system....split hoses, etc

Thanks for the reply. What’s the best scanner to use on a Nissan? 

I use iCarSoft which is just fine for Nissan and most other makes

They do a deal on 10 makes to download (your choice) .... very cheap for a tool of this quality
