So was messing around with the engine today. I had the MAF disconnected and had the throttle @ about 35-4k. Let it go back to idle and it up and started idling funny and then quit on me. So I started it back up, which it didnt really want to do. But when it did start it was idling @ about 4 or 500 roughly. And thats when I noticed the OP gauge was at zero. I gave it a little gas and the OP came up but as soon as I let it go back to idle, the OP dropped to 0. So I shut it down, put the MAF back on and started it again. Same results. So I shut it back down and started cursing. To me it sounds like a main bearing went on me. Im willing to bet SOME of the crap in the oil came from the cross brace under the oil pan. Like the sand pebbles. But not the really small shinny crap..... :rant: I gotta long weekend ahead of me. I just hope the crank is ok.
