[DML] JOSH'S BEASTIE BOY AND ACCELERATION PROBLEMS



Everyone in the group, THANKS for all your ideas.  I have spent the last couple days checking one item at a time, firing up the car, checking the symptoms, shutting it down and waiting for it to cool down in this 100+ weather we've been having every day, then checking another item.  

Many of you sent me in the right direction with vacuum leak ideas, but a special thanks to John Hervey and his persistence.  He kept pinging me to replace the WUR and after my third one, I am able to get full throttle.  Also, timnagin (Greg), from another forum, forced me to look at something I had never even touched or even looked at, the idle speed screw.  The PO Arsehole had screwed with this and never replaced the plug.  The idiot stuck a piece of kitchen sponge in there to keep out any dirt or moisture and air just sucked right through, but at the casual glance it looked like the hole was plugged.

So, here's where I'm at, I can start the car up, the idle hunts a bit (100-200 rpm), but I can get full throttle with minimum backfiring.  After it warms up to operating temp, I get full throttle, no backfiring, but the idle is hunting from almost stall to 1000 rpm.  I disconnected the idle speed switch and rpm goes to 1500 rpm and is rock solid.  I have not driven it yet to put a load on it since the A/C is down and last night's low was 82 degrees.

I'm replacing the O2 sensor as soon as the car cools down to see if that will will help the idle hunting.  Any other ideas?

Also, new topic.  I flushed the coolant system to get out years of crud and old coolant.  Took a couple hours, but everything was running clear when I finished.  I then filled the system with just plain water, cause I figured I'd probably have to work on this system again.  This morning, I fired it up and while I was waiting for it to get up to temp, I checked inside the reservoir bottle.  I have a white foam in there that looks like soap suds.  The water level is good, fans came one at the correct temperature, and it cooled down appropriately.  Any ideas on what is causing the foaming?
