Hi all, I started my Civic last night and the revs after a minute or two settled at 1000rpm which is normal but then about a minute later it started to rise to 1500rpm and then back down to 1000rpm and then back up to 1500rpm and then back down to 1000rpm. This was continuing for a couple of minutes with no change so I gave it a couple of revs to about 4000rpm (it was quite late) and when it settled back to 1000rpm it did it again. I then turned the engine off and restarted it again with no change. I have not driven it for quite a while now (at least two months) but I have been starting it from time to time. I have'nt tried it today yet as not long been back from work and wanted to get some feedback first. No engine management light has come on and I was a bit dubious about driving it until I got some of your opinions. It could be I just need to take it for a GOOD drive (I hope!).
