mine drops after put in a gear...
I always thought mine idled around 1000rpm, but after one visit to a shop, I noticed it actually idles around 1300rpm when started and as soon as I put in a gear (I have auto), that's not neutral, it drops to 1000rpm. Sometimes it drops 900rpm and almost sounds like it's going to stole out, but it idles at 1000rpm. However, if I shift from Parking to Neutral, it still idles at 1300rpm.
I could be wrong and it did this ever since I owned it, but I noticed this after a shop visit.
Is this normal? Someone said I might have a vacuum leak, but this shop tested and looked at other cars and they said they all do this...
