Problems with Idle Revs
Hi Guys,
I had my car serviced at the Nissan Service Centre in Haberfield (50,000km). I asked them to also look at the idle revs as they appeared rather high (just under 1,000 revs). Looks like that is normal though... But, since then the engine displays some "interesting" behaviour. When starting up the revs go up to ~2,000 and stay there for a few seconds before dropping back to around 1,500 for a few seconds and then slowly going down to around 1,200/1,000.
When taking the foot off the gas and pressing the clutch (like one would do when shifting gears) the idle revs stay where they were before taking the foot off the gas for about 3 to 4 seconds before going down to 1,500 where they stay for 2 or 3 seconds and then dropping to ~900.
When letting the car roll down a hill in first gear and the revs go up to 2,000 engine breaking is noticeable, the car slows down, the revs go down to 1,500 when the car suddenly speeds up again (up to 2,000 revs)
This is really annoying when approaching a red traffic light and the car stays in gear, it slows down until the revs hit 1,500 when it suddenly starts speeding up again.
This started happening after i got the car back from the Nissan guys in Haberfield. Their response to the first inquiry why the idle revs where to high was that some floating "thingy" was extremely dirty and had to be cleaned. Now I am not sure that that was the correct diagnosis. I am not taking the car back to them as I amextremely unhappy with their service (didnt do things they were supposed to do, did things they were NOT supposed to do)...
Do you have any sugestions what the problme could be? I have booked the car in at Rockdale Nissan, but I would like to know what I should tell them where to look :-)
Many thanks for your help,
Wolfie

Re: Problems with Idle Revs
Hi Wolfie and welcome to the forums.
As Rich suggested above you can either reset the ECU yourself or when you take it to Rockdale Nissan ask them to do that for you. It's free of charge.
Please feel free to visit the Introductions section of the forum, and tell us more about yourself when you have time: Introductions

Re: Problems with Idle Revs
Hi Brett,
Could this be related to the timing advance you have recently asked the dealer to do and which may require you run on higher octane all the time?
