Cleaning Throttle Body, 2.0T

**sriturbo** · 14th November 2008, 11:37

Normally when I'm cleaning a throttle body with spray cleaner, I remove the air filter and spray the cleaner up the air intake to clean the throttle body a bit.

Can this be done on the 2.0T or what is the best option for cleaning the throttle body?

Also how often are the spark plugs supposed to be changed on the 2.0T Z20NET?

VX recon 10k on the spark plugs

But for what they cost 15/20k will do.

Funny you should say that tho. My mechanic changed mine when I got it serviced in August. I've done 19k miles in my Ed100 this year and he asked if it'd been running rough. I said it been ok but then driving it all the time I might not notice a decline in performance. He said the plugs were well knackered (showed me them and they def looked shot) and I should consider changing them every 10k as he thought 20k was too far. I've used him for years and he's superb so I'm inclined to agree. 10k nearly done again so it'll be off for a change so we'll see if he's right. (yes, 10k in 3 months, scary!)

With the cars running BSR stage 1 15k is ok! thats what mine did but the tech did say i was silly to change them!(they were ok)But with stage 3 10k sounds ok.

You won't be able to do that on the 2.0T - there's the small matter of a turbo sitting in between your air intake/filter and the throttle body.

If you need to clean it then the best bit is to remove the boost hose going into it and clean it that way. You'll see the butterfly exposed when you remove the big boost hose - TB is situated on the front of the engine under the engine cover.

Thought about doing it this way on our 55 reg Facelift Club with the Z18XE engine with carb/injector cleaner spray...about 35K on the clock...did/do you run the engine at low revs (about 2K)while spraying the butterfly and throat until clean ??? Or did you clean it 'closed' and mop-up the fluid left in/on it???

Comments would be appreciated...

Thanks & Cheers
