i no many of you have cleaned your throttle bodys. what i want to know is when you guys took it off to clean it did you buy a new gasket or just try not to damage the old one?
-
When I did mine, I was just careful with the old one. No problems yet.
-
I was careful on removal and then smeared a very light coat of instant gasket sealant over it when I refitted it for peace of mind.
-
I have a spare throttle body in the shed and just change them over and then clean the dirty one before it goes back in the shed. I have changed mine close to a dozen times on the same gasket with no issues yet.
-
Diden't even take mine off TBH! just sprayed carb spray a few rags and a toothbrush. open the throttle to clean both sides. waited 30 mins before turning the engine over worked a treat.

ok nice1. shall have ago at it this week somethime then. cheers peeps :wink:

I did mine a couple times with the throttle body on using Wynns Car and injection cleaner. Did it with the throttle flap closed and then again with it open. Started it run and let it tick over a bit roughly at first and then blipped the throttle all good.
The next time I removed it, cleaned it again and used a flap sander in my hand held drill and ported it out a bit on bot sides being careful not to go to close to the flap. Refitted using gasket sealant and noticed a slight improvement.
The third time I did, I removed it again, took out loads of metal with the flap wheel again in the drill and knife edged both sides of the throttle flap. I also opened up the inlet manifold to match the throttle body. When I refitted it this time though I used gasket paper which I matched to the throttle body to ensure a good seal.
This time before starting I had disconnected the battery for an hour before restsarting. I am sure it felt smoother and I've noticed much better fuel economy too. Unsure if any REAL power gain, probably just smoother running as I've not done a before and after dyno run. Coupled this with the air box mod it feels so much better than standard.
Passed emissions too on the MOT no problem as well.

NOOB here <--- point and LOL :rolleyes: But whats this taking out loads of metal all about? thanks

The throttle body has a hump inside it, if removed CAREFULLY you can de-restrict the airflow through the intake. Take too much out though and you risk ruining it completely and your car will run like sh!t.
-
Totally agree. It will run very poorly with a lumpy tickover and very poor low speed running.
Be careful or you'll ruin it as the previous guy said and you'll need another !
-
wont be doing that then, although i heard i can put a 1.8 throttle body on my 1.4 and it make a difference but lets face it only thing to make a difference on a 1.4 is a GTi 16V lol
