I have a 1999 Odyssey EX and as I was trying to replicate another problem (engine stalls out while driving down the road, put back in park and starts right back up) I caused another problem (problem 2). I thought problem 1 was the result of a bad ignition switch so as I was driving I was messing with the key and finally got it to stall. The problem now (problem 2) is that I can start it up but it wants to die out. I can start it up and give it some gas but if I take my foot off the gas it idles really low and or stalls out completely. I noticed that if I take the two vacuum line off the back (firewall side) of the intake manifold, it will idle higher and almost normal. Also, I can take the vacuum line off the side of the throttle body and it idles fine. Is this a problem with the idle air control valve maybe? Any help is appreciated.
