I'll let you fellas know how it goes (..try it this weekend).
I haven;t had any TB TPS problems though. Once the idle holds, it hold steady at about 500-600 RPM, nice and smooth too.
You know....I failed to mention another thing. When I start cold, I also hear like a 'detonation' coming out from under intake or exhaust, almost like an internal backfire. Could it be I'm running lean as the result of a dirty Mass air sensor..or is it really the O2 sensors?
Mr. Jester ; I'll try the ol' spray thing on the MAF.
XBAJBUSX: With a voltmeter, check the TPS on your throttle body. Your volt setting may be off too. With a Phillips screwdriver, you can adjust it to 0.8V (Is this it guys? someone please verify this setting, and help out XBAJBUSX! thanks!)

Happy Stanging!
