sorry i didn't get back, i was in vegas- it was awesome. anyway yeah that's the valve i fixed. i didn't know it will go bad so soon i might save a little and go ahead and buy one from honda, but i have to see if it has a part number on it or not, or if another one from another motor will work b/c i had a little trouble trying to order other parts, i'll see how that goes.
what about some threak locker?? i wonder if that will work next time it happens at least i'll know what to do and i'll try some threak locker.

You should reset your ECU...

For me it usually works for a long time. I have no idea on the thread lock, but you have to make sure its compatible with the plastic valve. It would seem that it would work, but I would use it sparingly. You don't want it stopping up the valve. Maybe even a small dab of heat proof grease, or rector seal (plumbers pipe dope) would work as an alternative.

A mechanic once told me that Honda uses a wax on it. I have no idea if that is true or not. It doesn't make sense to me given the temperatures the throttle body reaches.

I have a 90 CRX SI with a d16a8 or a9 whichever is dohc...just bought the car. i had surging idle from 2000-3000 rpms so i replaced the MAP sensor and the IACV. I fixed the surging idle until it completely warms up then it starts again. so i figured it could be the thermostat, im replacing that tonight. does anyone have any sugestions in case that doesnt fix the problem? It doesn't have a FITV so i cant fix that lol. The only thing i have not replaced is the TPS. please let me know Thanks a lot
