i am but i have a 92-99 NA and will try it but i want to know the best way to hook up hose/ Cleaner then ill do it and post results

look for a rubber hose going into the TB. If you take it off and its empty (air), thats what you want to use.

Thats like russian roulette! :?
Follow the hose back just to make sure it does not have a yellow tage with "CAUTION FUEL" on it anywhere because those can run close to the TB...

yeah, thats probably a good idea. I figured you would smell fuel if you took one of those off.

I know i mentioned long ago that i was going to do this thing soon enough and i'm sorry that i still have not. In any event i will be doing it within a week or 2 (again sorry for the wait times :() but i'm 100% sure on where i'll be hooking it up on my NA::

I'm doing just what i stated in earlier posts for my NA engine,: Hooking it up via my PCV valve hose. Any hose coming from the TB works, PCV is just most easily accessable for me so that'* my choice.

As for the O2 sensor issue, lots of ppl in this thread are saying the GM top engine cleaner is safe for them so I'm not too worried.. but if people are that scared then why not just remove the o2 sensor from the car, plug the hole in the exhaust header with a big bolt of the same size, and run it? I wouldn't bother but that way, if you're so worried bout the o2 sensor, it wont even be there during the run. (i'd unplug the o2 sensor altogether to ensure the car runs in whatever safe mode it has for a lost o2 sensor)

p.*. I will not forget this thread and hereby swear to update it whenever i do the clean!!!!

your car regulates the A/F ratio based on o2 numbers in part, it might throw a code or not run at all.

If you're worried about new plugs, go get some old ones.

You did save the old ones, right?

Heh, I have the last 4 sets

or get the cheapest ones you can find (they only have to last for like 5 min)

Hmm...the ones i use are only about 1.25 a piece anyway I just hate regapping them.
