i've got a f22b non vtec in a pelude that idles high at times of the day that it shouldn't, like in the middle of a sunny afternoon after i've drivven it three times already(1500rpm). at other times it idles normal. it also is slow to lose revs when you let go of the gas pedal. if it was carbed i'd say that the auto choke was stuck, it's that kind of fault. also it seems to chew through more gas than i would think that it should. any ideas would be good.
cheers
