Thanks

Not an expert by any stretch, but thank you for the compliment.
You also have to remember (as you were following my thread) I did a number of other items which may have helped with my idle problem.....
such as....
1-checked for vacuum leaks
2-replaced the rubber connector under the plenum for the canister line
3-replaced #8 spark plug wire, as it was not giving me an ohm reading and was corroded in the plug end
4-repaired #7 spark plug wire at the coil tower end, as it would not make a secure contact, and would pop up slightly when attaching.. A squeeze with the pliers on the outside of the boot corrected that problem
5-and the now "famous dag" application after I completely cleaned the inside of the TB which your not supposed to do.... but I figured I take a chance and get to learn something in the process. As I have mentioned, to seal your secondary blades with the "dag" takes a lot of time and patience to make sure the blades are sealed in the bores when in the closed position. It took many applications (some minor) to fill in the gaps. I think I accomplished that, but I feel I also got lucky as it has worked out for me...

So I can't really state what corrected my idle problem as when each item was completed it was not tested until everything was done. Looking at it from a logical standpoint, I would probably have to say that the "dag" application played a role in correcting my problem. But then again, my secondary blades were pretty sealed from the original "dag" from the factory. So I really can't point to one correction that made the difference, but whatever is was, is now working....
Again, I hope you get squared away....looking forward to your results.....
