Default TB cleaning and a little more .. install complete, UPDATE

Today I finally was able to clean the throttle body in hopes of at least fixing my rough cold idle. Instead of just cleaning it I planned on doing some "porting" and polishing. I didn't really remove much material, I mainly just focused on one section, and then polished the hell out of the rest. So here are some pics..

Took off the TB and was disgusted with the SC inlet. Someday I'm removing that and cleaning it. I did clean a little of it while it was on the car. Don't mind the coolant in the SC, it got inside while removing the TB

I removed the plate to clean it better. Reinstalled and cleaner than ever.

Here you can see at the top where I removed some material on both sides. I didn't have "ideal" dremel attachments, just sanding cylinders. It isn't the prettiest job, but it'* smooth and much more rounded at those edges. I polished it by hand with 1000-2000 grit sandpaper since that'* all I had. It wasn't that hard either.

Cleaned and painted on the outside...ready to install! No pics of it installed yet...got dark, and I need to get the right socket to fit my torque wrench I tightened it very well without the tq wrench, but tomorrow I will get the right socket and torque it to 89 in/lbs. If anything, right now it is tighter than needed, but I want to know for sure.

I can't WAIT to get the intake on! Should make a substantial difference, not to mention the cleaned up TB.

Your welcome.

89 inch/lbs? You have an L36? Try 18 ft/lbs.

Thanks Bill! I was on the phone last night w/ Bill as he was explaining the process of porting/polishing the TB, among other things.

89 in/lb vs. 20 ft/lb has been a debate. Check out my 92-99 TB thread...

Nice to see my SSEi is getting the dire attention it needed.

<--- much happier now that the car is a primary car instead of a 2nd car

Great work Pete!
