[DML] ACCELERATION PROBLEM UPDATE WITH JOSH'S BEAST

[mike clemens <rmclemns@xxxxxxxxx>]

Okay, some history first, since several folks have asked.  Josh's car was originally sold in New York and was driven there for many years.  Then it made it's way to California and then to Oklahoma and now it resides in Arkansas.  My best guess is that before I started working on it, it has probably been 10+ years since it last ran under it's own power.

Here's where we are today.  I utilized many of the ideas that the List provided to try to solve the backfiring and bogging between 3 and 4000 rpm, but one hit the nail on the head.  Thanks to Ken K, he suggested I push down on the air metering flap, while at the same time, giving it throttle.  RPM's went all the way to red line-----yea.  He also gave me two things to look at----a vacuum leak and possibly the cat plugged.

Well, when I snapped off the O2 sensor, I decided to go ahead and pull the cat, since I was already there.  I was able to remove the cat and when I looked inside, I saw a mud dauber nest!  After about 5 seconds of trying to figure how they got in there, I came to realize that it really wasn't a mud dauber nest at all, but the cat had overheated and melted the 'guts'.  Since the cat was useless, I gutted it and reattached everything, including a straight pipe in place of the muffler, just to see if this fixed my problem.

Answer----nope.  I still can't get full throttle and now the idle is hunting both cold and hot.  (550-950 rpm)

I'm down to this last thing to get BB running 4.0 and out of my shed.  Any ideas will be greatly appreciated.
