Hello. I have a 2004 Honda Odyssey....I just recently took it to Honda and they couldn't find a problem...The first time the car acted up was when I had got stuck in the snow after our major snow storm when I had been stepping on the gas while spinning the tires and then trying again in reverse.....Sometimes when the car is in park, the RPM's will rev up to about 1 1/2 and then drop, rev and then drop repeatedly....for no appearant reason....Recently it has started acting a little funny while driving....Say I'm driving and accelerating the gears seem to shift fine, but if I back off the gas pedal the RPM needle will drop and kind of flop up and down for a few seconds...Honda guessed it was either the Idle Air Control or the Throttle Body....They cleaned a whole bunch of carbon off the idle air control and thought that might fix the problem, but it seems to be getting worse....How do I know which is causing the problem? Thank you!
