Ok now
You gotta repair that manifold leak! That leak has exhaust coming out of it on the exhaust stroke and then it has AIR going back inside during the rest of the time. That air can burn a valve! The extra air makes a really HOT fire at the exhaust valve.
If I could SEE the crack I'd WELD it in place and see what happens. But fix it you must.

Finally!!! I took the IAC off and cleaned it with my $10 can of cleaner and started the ole rust bucket and it idles perfect. Anyone with idle probs should do that first. Took maybe 10 minutes. Thanks Guys for all your help!
