Ed, Here is what Unca Joel had to say about cleaning that stabilizer - I haven't tried it yet but I trust his advice: > *there's another culprit that can cause the same symptoms! > the idle stabilizer VALVE. it's that round brass-colored cylinder > thingie in the top kinda-middle of the engine. it has two black hoses > going into it and one electrical connection (looks like a fuel > injector connection). what it does is allow extra air for cold > running. and it then closes a little valve/door inside when the engine > warms up. sounds like yours might be stuck closed ... that can happen > over the years due to the grime/crud built up from the fumes that come > from the engine crankcase (that's where the extra air comes from).* > > *and since it's cheaper to clean this guy first, try it. ;) get a can > of generic carb cleaner, and remove the valve from the engine (cleaner > to do it that way), and spray LIBERAL amounts of carb cleaner into the > openings where the hoses were connected. shake out the excess, let it > dry a while, then do it again. then again. then again. :) usually four > or five times is enough to free up the little valve/door thingie.* > > *besides, it probably needed cleaning anyway. and it (valve) is VERY > expensive to replace (like $200)!!! :( > * > -- Thanks, Jeff '90 Carat (Grover) '86 (We call this one Parts) '85 GL (Preparing to move to a new Home) '78 Bus (Melissa) Patty's Bus
