Advice on cleaning throttle bodys

Hey guys, need some advice. I need to clean my throttle bodys but I dont want to mess up on the reset procedure. I have no OBD2 bluetooth to determine the temp of the vehicle which is important during the process. So if any one who has done this with out knowing the temp successfully plz let me know how ya did it. Thanks in advance

I literally did this process 2 weeks ago and everything ran fine. My car was misfiring, running lean and had an air leak... Turned out when I checked my air filters a bug fell into my intake then flew into the MAF and shorted it out, causing the issues above. It was crazy but I saw the bug, removed it, but also did throttle bodies since I had the intakes apart and the below is fine.

1. Pull off throttle bodies and clean them while still connected. Yes, you can push the valves and open them to clean inside, they will rotate back to their original position once done
2. Do the throttle body relearn here

You don't need exact temperatures, just follow the video.

Ok n thank you the advice, a bug in you MAF is f-ing crazy. I had my battery cap pop off bounce around my engine bay before it stuck itself in the fan n blow it out lol. Crazy sh*t happens lol.

Unscrew the 4 hex screws and intake tube but leave all the cables attached.

You don't need to remove the throttle bodies to clean them. In general, I try to be as minimally invasive as possible.

When you say remove do you mean disconnect the cables? If so, I would agree.

If not, it is completely fine to pull the hex screws off and clean it like in the DIY. It's also fine to push the flaps to clean the carbon that can causes them to slightly stick when they close. You gotta move those flaps for a full clean.

The Allen bolts that hold on throttle body will let you clean both sides of the butterfly valve. You have to remove the throttle body when you change spark plugs so you might want to change them same time
