throttle body cleaning.

I am going to attempt to clean my throttle body myself and was wondering ...

can it be well cleaned while its on the car, or should it be removed ? If I clean it when it's on the car, is it necessary to put a small brush inside the part ?

If there are DIY instructions avaiilable, please point them out cause I searched expecting to find some but didn't. I know where the throttle body is and THATS ABOUT IT !

Thanks

remove it. all you will need is a new gasket, which is like $4 at any auto part store.

i would remove all of the sensors, as well as the throttle cable. then scrub it with a wire brush, then with sand paper. you can remove the butterfly also

If you want to do a good job definitely remove it. I would shy away from messing with the TPS. It's a PITA to install and calibrate properly. Also wire brushes and sandpaper can be easily abused so if you are not confident in your skill go with something less agressive (scotchbrite comes to mind). Finally automotive stores sell dedicated TB cleaners but I have always found GUNK Engine Brite to do the best job. For the crowning touch use the foamy one. Easy around the sensors with this stuff. Good luck!

Arent the throttle springs on the right of the throttle body connected to it? If so will it come off as a full unit away from the throttle body, or does it stay connected once you get it off?

Well... There are several coolant lines and electrical plugs that need to be disconnected and the cruise control and the accelerator cables but you can remove it from the intake manifold. Make sure you have plugs for the coolant lines or drain some of the coolant. Messy otherwise. Coolant bad for shiny engines parts

well I keep looking but have not touched it yet. Bought a Haynes manual, almost useless. I am sure I could remove it and clean it, its just that I dont trust that afterwards the car will start ! A dealer would probably charge me $120 and who knows how well they would clean it. I wish I had a mechanic !

Go to advance auto and spend less than $10 on a gasket and throtle body cleaner. Remove the accelerator and cruise cable. Detach coolant and vacume hoses. After this you only have one sensor to remove. 4 bolts and the throttle body is off. Then clean it with the tb cleaner and a tooth brush. Tighten the idle adjustment screw and count the number of turns to tight, then remove the screw. Spray the claner inside the screw hole. Put the idle adjustment screw to tight and then back it off the same number or turns you used to tighten it earlier. Reinstall throttle body and all lines with a new gasket. Make sure you clean off all of the old gasket. After it is all hooked up start the engine. Adjust the idle adjustment screw until you idle between 700-750rpm. Now you are done. Enjoy!
Later!

heres a tip. when you remove the coolant line(theres 2 of them if you didnt do the trottle body by pass thinyg) just shove them in the bolt where the trottle body hangs on.

like, theres 4 bolt, just stick the coolant line on the bottom two.

I just had mine off the vehicle. The gasket P/N 161-P5A-004 is $3.24 from Acura of Augusta. You shall need a torque wrench to reinstall (16 lb-ft). Be careful in the removal of the Cruise and Throttle Cables; loosen only the inside nuts so that the cable adjustments remain as they are. You shall need to block the coolant hose lines as coolant is not good to get on belts.

What! You giving up already?

What made you think that the throttle body needed cleaning in the first place?

Actually if you aren't comfortable in your abilities you should find a friend for comfort preferable one with some mechanical know how. This is not a hard job but if not done correctly problems with the engine running and idling will ensue.

ok, here it goes...
IF I MISSED SOMETHING, LET ME KNO.
Cole, you have IM,regarding your pictures.




if you take a look at the cables, you'll notice that theres a nut at each end of the 'holder' so a person can adjust the cable. just lossen the inner one(closes to the the back, viewing from the front)
to get the cables 'unhooked' from the levels, just pull the level (WOT) and slide it to the side) and another, dont forget to 'mark' which cable goes to which side.

when you remove the coolant line, theres gonna be some seepage, clog it w. a bolt or something. and make sure you fill up wat came out and bleed.

now cleaning, just use some carb&choke/trottle body cleaner and a toothbrush.
and bout the idle adjustment screw, i didnt do it but if you want to you can.

installatin is reverse, just remove the old gasket and replace it w/ a new one.

good luck
