anybody know, or have an idea...

what might be causing two things to happen that i'm having issues with?
thing one- when coming to a stop the engine idles all the way down to the redline, radio shuts off, blower motor shuts off, and the rig feels like it is going to die. so, i either have to rev it up, or after a second or two, it just sorta comes back up?
idle adjusted, and a vacuum leak was found and fixed when it started, but then it has come back, and yes, i've double checked the vacuum leak. still fixed.

thing two- when driving, and in fourth, on occassion there is what can only be described as a "slip" that will happen, almost feels like the truck is downshifting, then back to normal, and may not happen again on the same drive, or might happen a couple of more times.

both of these symptoms are new, like less than a week and a half old, and i'm perplexed. are they related? completely different? hopefully somebody has an idea, this one is frustrating...

couple of things... 1984 fj60 2f, just had to have the harmonic balancer replaced again, as this is the fourth time the big pulley has come unattached. also, new arb in the back, less than three months old. new ome, same time as the arb. other than that, a week ago longboard was running and driving just fine.

thanks for your time

thing #2 - clutch slipping? Maybe the 2nd barrel in the carb kicking in?

ok, i can check the clutch, but it's only happening at random times, not anything i can reproduce. but it's something i hadn't thought about. thanks.....

Did they do anything to the fan clutch when they did the harmonic balancer? (That's a wild guess because I am sure that you are familiar with the fan clutch going on and off).

Don't have a clue on the first issue other than to be sure to check the fuel cut solenoid.

can't see why they would have, but how would that create a "downshift" type feeling? asking to clarify.

The way I read it, Heartworm is looking at the fan for a reason your HB keeps going south. ( fan out of balance, perhaps)

As far as #1, 60's have an "A/C idle-up solenoid, right?" ( likely not the exact name, but someone else can clarify if needed). You say the blower stops, so I'll assume in Aug that = AC is running. Therefore, it's a simple adjustment. Being a 62 owner, I'm not clear on where to do the adjustment, so a quick search should get ya the info you need.
#2 is too vague for me. Do your rpm's vary greatly during these "downshifts", does the motor stumble, etc. The more detail you can add here the better.

Searched for ya, apparently others are recently having similar troubles:

Read starting from post #7. 2mbb to da rescue yet again!

nope... not the a/c idle solenoid, that's the first thing i checked. but what i didn't think of was the alt. belt might be loose, since it was just off, so that when i stop, it's not spinning the alt fast enough? what do you guys think?
