Cleaning throttle body

[andrewrobert87]

Gonna have a go at this on the weekend, what sorta stuff shall i use to clean it? also, shall i use some WD40 on it to grease it up when im done?

is there anything i should look out for - ie - oil on the inside, dirt etc?

When me and a friend did mine we just unbolted it off sprayed it with WD-40 and scrubbed like made with tooth brushes all over wiped it all down and stuck it back on... No problems

Sweet, trying to cue a slight missfire / lumpy idle when warm! next port of call after the TB is seeing if i can clean the TDC sensor, if it can be cleaned :|

also, did you remove the sensor from above the throttle pedal? ive read that removing this and cleaning the ports can help with a funny idle

 

[Chapster5]

Ah, now mine was a lumpy/hesitating idle but mine turned out to be my breather pipe had fell onto the pulleys and worn through... Trip to the scrappy later and all fixed

Is that the thin pipe that comes off the air flow pipe from the air box, and goes behind the block? lol

Carb/throttle body/brake cleaner will all work.

Sensor and pedal come off as a complete unit.

Yes.

Mine was a pipe that comes up from a long rectangle unit in front of the drivers front wheel

As what JackJack said Carb/brake cleaner to clean it. WD40 even when wiped away will leave a film for crap to stick too

 

[andrewrobert87]

I didnt know that, ill get some carb / brake cleaner tomorrow.

That's the carbon cannister.

That's the carbon cannister.

It's that what went ay wol on mine made a hissing noise too

clean with brake cleaner, then grease the spindle ends. If you dont, the bushes the spindle sits in dry out

I cleaned mine this week, it was fairly dirty but this is how it looked after a bit of wd40 and elbow grease

 

[andrewrobert87]

Is it best to take the TB totally off the car or leave it attached when cleaning it?

 

[Chapster5]

Off it gives you full access all round to it

 

[JackJack]

Defiantly off mate.

 

[andrewrobert87]

Did this today - it was not that dirty but its clean now, made no difference lol oh well, didnt cost me anything to clean it up!

Nice to know considering I was gonna do mine on Sunday. How long did it take in total? I have cleaned mine just by taking air pipe off, with carb cleaner, and it made quite a difference, but always wondered whether taking the whole thing off would be even better.

just took the air feed off, unplugged the switch from the bottom of the TB, un-screwed the 2 bolts at the bottom with a 10mm torque rench bit, then did the top two, then it comes straight off. then use the carb cleaner and jobs done mine wasnt that dirty to be fair. car sounds nuts when you rev it with the air feed de-tached though
