Default Throttle Body Cleaning

I presently have the throttle body off the supercharger. I remember seeing in a thread somewhere and am unable to locate a post that said something about avoiding contact with some part in the throttle body when using throttle body cleaner. Can anybody advise me what that part is and where it'* located?

REMOVE MAF Sensor, make sure MAF is off...probably not a bad idea to remove the TPS as well and IAC to clean the motor and lube it a little.

Unbolt all the sensors and soak it in gasoline overnight. Then, scrub the barrel with fine metal brush. Once out of the gasoline, rinse it with water. Once it dries, install all the sensors. It'll look like new.

I'm not sure what an MAF sensor (maybe a fuel sensor?), TPS (maybe throttle positioning sensor?) or IAC are. Please elaborate.

Thanks

I can unbolt all the sensors and soak in gasoline. Then, rather than scrub the barrel with a fine metal brush, can I just use throttle body cleaner?

Yes, please remove the MAF. Or you will end up shelling out 120 bucks like my cousin did when he destroyed his on his lumina.

Well I took them all off and wouldn't you know it. On that last screw I noticed it was tight and went really slow.......bam, it broke and not enough thread left to grab onto. Anyone know what size it is cause, I'm going to have to drill and rethread. I think it'* about a 8/32 NC? I don't seem to be having much luck with this Bonne. It'* the 95 SSEi I'm working on right now. :(

Hang in there! The 95 is a good car and once you finally get past all these kinks you won't regret it!

Not sure on the size, but if you haven't figured it out by tonight, I'll get it to you.

Don't worry about 1 broken screw. I broke 6 on my 88 S10 Blazer. The 6th finally got me mad. I broke the 2 on the TPS, and the 2 holding the Dist cap down, and the 2 on the ignition module.
