Default TB cleaning: Why it took so long to do.

Vikings had a bye week so I thought I would clean the throttle body. Everything went well until I removed the first screw holding the IAC in place. It felt stiff as I was unscrewing it, and dang if it didn't break off. The second one came out OK, thankfully. There was a littl bit of a stub that I could get a small vice grip on, so I filled the back side of the screw hole (thankfully this is a through-hole) with PB blaster and let it sit overnight. The next day I tried to twist it out but no luck. I ended up drilling it out, which was difficult because of the hardness difference between the screw and the trottle body...I was not able to drill down the dead-center of the screw because I don't have a drill press. Anyway, the fix is shown below, along with before and after cleaning of TB. This TB had 107,500 on it. Glad the screw in the other hole came out OK because it is not a through-hole and would have had to be rethreaded.

Not that I can tell. It has always idled really well, and I just did it because..well you know, it'* that motorhead thing. You cruise this forum for awhile, and you just HAVE to do it!! It does seem a little more responsive on throttle.

I used Gumout TB cleaner, but it does not work very well. I started by carefully "shaving" the thick stuff with a knife and chisel, and then used the cleaner with toothbrush and Q tips etc. Finished with a nylon wheel on my Dremel.
