hey all, went to a track day today and on the way there it was fine when the clutch was pushed in it sat on 1000rpm but after the first 20 min sesh it has gone to 2000rpm when sitting there idling and has stayed that way for rest of the day the cars a r34 gtt and has a microtech lt-10 in it,just wondering if anyone knows what would be causing it? everything else seems fine,any info would be good cheers
