For people who have never done the TB cleaning, please take care and note the FSM precautions regarding removal of the TB and remember it's electrical and mechanical, cut the juice and don't force the plate around. It is possible to do some expensive damage if you are totally careless.
Pre-cleaning:
back side of TB:
This build-up was causing the car to die at idle on throttle lift. Once I cleaned this out, no more problem. It had never been cleaned in 5 years/50k+ miles.
Clean(er) - I didn't do an **** retentive job on it because I was trying to see if that was related to the idle problem, and it appears it was, pre-cleaning you could not even see light around the edge of the plate. After, something maybe ~1mm or slightly less gap all the way around.

And periodic cleaning the TB does need, I was surprised at the amount of crap in there. The small space around the TB plate was closed up. IIRC when the car is at idle the air it uses comes through that small gap between the plate and TB.

also, i did not put any into the tank because 2 tanks ago I had already added some Lucas Oil fuel injector cleaner stuff
i did in fact pour some seafoam into the crankcase oil last night, and then I had the oil changed today

this is the response I got from SeaFoam guys about fuel treatment
The video show a general application for adding to fuel,oil and in a vacuum line. If you want to truly treat your fuel for cleaning,moisture control and adding upper cylinder lube then the ratio should be one ounce per gallon to get the best results.

i just wanted to point out that on honda motor's that have already worn piston rings/seals seam-foaming can actually make the situation worse, by removing the carbon build up it actually lets more blow-by past the piston thus burning more oil than prior to running the seam-foam, ive used it in all my car's and never had any problems but if your motor is already burning more oil than usual i dont reccomend usuing this as it could potentially cause it to consume even more'....
basically if your motor is already hurt do not think this will band-aid it and make it last longer...it could potentially make the situation worse..
On a second note, ive always had good experiences with it, i prefer to run it through the vacumm source and crank case vs the fuel tank but it can be done to all 3'. Its recommended you let the car idle for 5-8 minutes after using the sea foam and then take it on a hard spirited drive for 5-10 minutes....bring it home and change the oil....CHANGE THE OIL AFTERWARDS.....i just got my g35 last week and havnt peeked around the engine bay yet due to weather so im not sure how much of a pain it is to change the spark plugs on these car's but if its as easy to do as it is on a honda id also recommend you put some new plugs in as well
