Noticed something strange yesterday morning on cold start, was 12 degrees and the engine holds the revs a little higher when cold (like the auto choke on old cars) normally after 4-5min of driving the revs will settle just above the 500rpm mark (must be 600 or 650rpm) , but for some reason they were sitting at the line down from 1 on the tacho which must be 800rpm for the whole 15min drive for school drop off. (I did have the heater going on the feet but not the AC on)
When I would slow down and come to a stop at the lights in manual the revs would rise to 1,000rpm and then slowly drop to 800rpm, on some occasions that would fluctuate from 800 to 1100 to 1000 to 1100 before coming back to 800.
On the drive back from school drop off everything went back to normal and it no longer idle high or had fluctuating revs. Has anyone experienced this? Its like cold start was stuck on? I think I read somewhere and I think it has happened in summer when the AC is on, sometimes it holds the revs at 1,000 before dropping because the AC is on?
I havent had a chance but will pull the Walkinshaw pod filter off, check fitment and clean the butterfly.
