Hi John thanks for the pics; everybody worldwide can read Pics.
If you could post a pic of the TB mount. flange on Intake, w/ TB removed, that would be Great.
Let's keep it Simple for now, would advise not dealing w/ MAP sensor just yet. Your Grooves look OK, but might want to see if Groove is full depth throughout both Grooves. Take the bit ya used, and hold in each Groove, roll it left-right thru to see if the taper of shaft touches flat edge of TB bore. High spots- can carefully re-Groove to cut down high spots. Be sure to hold tool Very steady when cleaning up a Groove. DON'T let bit swing around in any direction, also dont get too carried away in cleaning it up. Real easy to over-cut it, Groove can get rounded-out and loose it's intended shape. Ya want bit ideally to fit in Groove full depth where taper on shaft touches bottom of bore wall, AND the bit can't be rocked or swung left/right very much.
Better to have Groove have some imperfections than to over-cut it. This stuff just takes practice. So John just check the Grooves w/ bit, and remove only the worst high spots where bit isnt full depth. Remember in training DVD where Ron just does ONE clean up pass right to left?
Also be sure you "check your work" shine bright light inside grooves and from outside in dark spot, and look close for any breakthroughs. Patch any w/ a bit of epoxy. let dry then carefully recut any epoxy in Groove. ALWAYS check your work every time!
OK I looked at pics again, looks like bit shaft dug in to bore wall several spots, usually means its full depth there. Just check Grooves w/ bit, go from there.I'd make sure I was happy w/ the 2 Grooves and run it!
Have ya done anything w/ PCV yet, John? Do you know about the computer Re-learn procedure? Those two will add lots to results. Also if O2's are over 50 K miles think about replacing 'em.
IAC port fill-in looks good! And--be ready to check for those darn Manifold Vac. leaks, these 2 Grooves are gonna amplify any there! Also Be sure IAC valve and bore were clean, gunk can cause IAC to stick open-not good. Ya probably cleaned that all up before filling in IAC pathway, just sayin"!
( don't mind me, I tend to over-advise on everything!
)
So John, a couple of decent Grooves your first time out! The IAC restriction may cause low idle RPM, but just adjust idle stop screw, or open hole in epoxy a tiny bit. Git 'er on there, any issues, just post 'em, we'll sort them out!
good for you, John, keep at it!
