Hi, I'm about to clean the throttle body on my car is there anything i need to do with the ecu once it's done like a reset? I've been readin around and some seem to say it requires a TBA (Throttle body alignment) of the ecu?
-
yeah. dont touch the tps (throttle position sensor) on the tb, leave it on when cleaning, just dont bang or drop it.
Take tha battery off, and when your done, hook it up and turn on the ignition, dont start it, there will be loads of whirring and clicking - when that stops, you can start the engine.
vag-com can force a tb alignment, if you have it.

TB alignment? On a Mk3 16v?
I don't think so...they are throttle cable, so don't need an 'alignment' as the 1.8Ts do.
It looks to be a 16v in the OPs sig.
You can re-code the TPS to the ECU...but shouldn't need to...certainly not after cleaning.
-
Ess - does this apply to the 8v aswell...???
As i really need to clean mine, and polish it with some nice metal polish from work.... :afro:
-
I took mine off, cleaned it up and then refitted with no problems whatsoever.

Not sure about SIMOS 8vs...but the early ones I seem to recall had a throttle cable.
16vs certainly do...along with early 2.8 VR6s and 2.9 VR6s.
When you hear polishing...it's not actually necessary to polish it up like a mirror...it's a poor term really.
You just need to remove any casting marks, clean up the air flow path etc.

Same here, for a 16v.... i tell a lie i had the throttle reset thru vagcom
-
whoops! soz lads, i am thinking of the fly-by-wire tb on the audi, doh!
-

Likewise, the simple undoing of 4 bolts and and some elbow grease is all that is needed here.
-
all mk3s have cable TB, so no need to realign.
-
Thats good news! Gonna get straight on it tomorrow then :smiley: Hope i notice a difference on the pedal.

sorry to hijack the thread but im thinking of cleaning my tb and have never done it before.
how do i go about it and what do i take off and so on. basicly what do i do?
any pics would be a great help.
-
as long as you dont take the tps off the tb ;)

Fairly easy Mate....remove the speedo cable, then remove the two air pipes from the top of the throttle body unit. Undo the four allen key bolts that hold the throttle body in place. Then when you can move the throttle body you will find there are two pipes under the throttle body still connected. One of these has water in so be careful when disconnecting these. Then the throttle body is off the car. Clean all the inside thoroughly with either carb cleaner or wd40m and an old toothbrush. Then reconnect the two pipes at bottom, replace throttle body and secure with the four allen key bolts, replace the two air pipes at top and replace the speedo cable and all done. Should take about 2 hours total. Good Luck Deano

great nice one mate.
forgot to mension mine is a 1.8 8v gl engine. is that the same to do?
-
Not sure Mate but would have thought so!!!!!
-
The only time the throttle sensor needs to be matched to the ecu on a mk3 is if its an auto.
-
like I said was used to the later fbw throttle, forgot the mk3 has a cable one.

think this is a task for me at the wkend.... ohh sh!te its valentines weekend.... I may do it at work on monday :afro:

Buy the missus a new toothbrush for valentines. Then when she is cheesed off and walks out you can use her old one to clean the throttle body. Job done :grin: :grin: Cheers Deano
-
lol quite funny that... i'll keep it in mind haha

I'm on with mine tomorrow after i'v replaced a very leaky sump gasket!! I looked at the diy thread for Throttle body porting but i think i'll wait till i've bought a spare incase i balls it up.
-
thats why i suggested to the op to get a spare

I have just done a complete TB & MAF clean on my mk3 8v GTi...for the 1st time. After all this talk of TB cleaning, I thought I'd give it a go...I really want to start getting to know cars better and service my car myself. I enjoy technical challenges and finding out how things work...not to mention saving da dolla.
As I said, I have never done this before...it took me about 1h 45mins, it really is simple. 3 pipes, 4 Allen key bolts and a clip-off electric connector...that's all. Took the TB + the pipe connecting the TB to the air filter + the MAF (being careful to leave it mostly in-tact!) off...took em inside and a bit of WD40, elbow-grease & 4 new duster cloths later and it was gleaming inside. Put it all back together, reconnected the battery, turned on the ignition (without starting it) for 30sec then it started almost instantly. I was a bit concerned at 1st, as it seemed to idle at about 2500rpm for the 1st few seconds...but after like 10sec it was back to just under 1000rpm.
While I was pretending I am a mechanic, I changed the fuel filter...was fairly easy to do...would have been alot easier if I had a ramp...but a standard jack + an axle stand for safety did the job.
Just been to take her for a spin, and what a difference! She idles much smoother, and there is no rev drop-off when you take your foot off the gas. Before it would drop down to 700 or so revs after you take your foot off the gas (not in gear of cause)...now it goes down to about 1350 for like 3sec then down to normal 950rpm.
Over all, I am very pleased...engine seems far smoother and happier. Not bad for a bit of tinkering on a Saterday morning...only one regret through...how the hell am I going to get all this oil & grease off my hands and out from under my nails?!?!? hehe
Seriously guys, if you have the tools I strongly suggest you do this...made a big difference and so satisfying to know that YOU did it!

im currently in the process of cleaning my entire TB and springs hoping it will fix my massive issue, big tip to get the oil off m8 put some suger in your hand about a tablespoon full, and add about a 10 pence worth of washing up liquid, add some hot water and scub your hand together :P
by the way whats the MAF?
-
Mass air flow sensor.

I do exactly the same but use salt!
I never got round to the TB today as i had the privilege of driving a Mk1 escort mexico instead :smug:

I removed mine today to have good access to the back area of the engine but while it was out I cleaned it. Also cleaned the areas I could reach of the intake manifold.

Went to clean the tb today but noticed a black silicone looking substance round the tb where the gasket should go could this be a liquid gasket?? I didn't wanna take the tb off after that incase it is. Anyway i took the main hose off to look inside and it looked spotless so dont see any point anyway.

Mine looked spotless when I looked but the car ran like sh!te. I took it off and cleaned thoroughly and you would be amazed how much gunk came out. The car has ran perfect ever since. As for the gasket these will be cheap enough to buy and I would get one first then take it off and clean and remove the old stuff. Cheers Deano
-
As Deano says above, mine also looked spotless initially when i first removed the pipe from the TB....but it wasn't until i unbolted it that i discovererd how much gunk was inside the butterfly affecting the idle massively.
-
Ahh right i will take it completely off once i've bought a gasket! Someone must have been desperate to use that stuff round there lol.
-
I have had a really lumpy tickover for a while now so thought i would give this ago...
Firstly this is a very easy job, secondly it worked.. ticks over really nice now..
Cheers Guys.. :smiley:
Next onto fitting the coilovers...

Why is it such a bad thing to remove the switch? I have already done so :lipsrsealed:
