I finally got my engine back together a couple of days ago and fired it up. It runs O.K. for about half a minute and then when the idle comes down, it starts getting worse up to the point where it will barely idle. I was told that it might be the O2 sensors because they might have been damaged by coolant going down the exhaust, but I'm not sure. It ran great before the HG's blew last fall, no check engine lights or anything. It did sit all winter in an unheated garage, but a sensor wouldn't just go bad from sitting would it? Any help is greatly appreciated.
Thanks,
Doug
