Title: throttle bodie clean :(
Post by: matg340 on 13 July 2010, 23:45: Hey folks , i decided today i was gonna do a tb clean as shown in the maint thread ,

I have an 99 1.8t agu and tbh the tb was bloody filthy ,cleaned it up like new put it back together and noticed the tick over had crept up to about 1200

Now it seems to be getting worse when its warmed up,mine is cable operated too so am i right in thinking it shouldnt need realigning ?

Biggest concern atm is i should be going to R-tech on friday for a remapp and im presuming this could be a problem ?

Has anyone else got same engine and had similar problem or anyone got any suggestions ?

Any help is appreciated folks

Post by: james2 on 14 July 2010, 00:07: the best way of cleaning it is removing the induction pipe get a friend to hold the throttle down and get a cloth with carb cleaner on and clean it out ...i would never take it apart as the problem your having.........get it to r-tech if you can they will help .........TOP BLOKES :drool:

Have you fixed the cable properly to the butterfly and also attached the pipe that atached on top ok? I know this might sound a stupid thing to say but some times these little thing are the corrs. :)

Checked all the pipes after they seemed ok , first thought was maybe leaking between manifold and tb so i ordered a new gasket yesterday
hopefully get that this mornin ,

While im there ill check everythin over again for leaks , car is drivable just ticks over too high , read on here and elsewhere that sometimes
it just needs to settle back down and after a few miles it sorts itself out ?

Anyway ill put the new gasket on and let ya know but thanks again folks

Post by: wratey on 14 July 2010, 10:40: My AGU did this aswell, it should settle down. Also try disconnecting the battery, leaving it for an hour or two then reconnect, worked for me!

Post by: Deano2711 on 14 July 2010, 11:31: Try disconnecting the power connector off the throttle body for about ten minutes. Then reconnect it and with the door open turn the ignition to position 2 and wait. You should hear a buzzing type of sound for about 10 seconds. When this has stopped start her up and see if that works. The throttle body will self adjust itself if you let it. Other than that just take it for a good long spin as advised by others on here Mate.

Post by: Hulmie on 14 July 2010, 11:47: your throttle needs to adjust. after about 100 miles will be fine. Nothing to worry about.

Will be fine at R-Tech how it is, it'll probs sort itself before you get there, if not the lads will sort it out.

Had a mate plug it in today and 2 faults found both relating to tb
The butterfly isn't closing properly on idle and at first he couldn't get it to accept the reset ? After 4 attempts it reset the idle and all was good however just noticed it's crept back up not much though !

Spoke to rtech today and chap I spoke to seems confident it can be cured so fingers crossed I haven't killed me throttle body , and all being well Friday remapp will be done :)
Thanks again folks

good luck with your map you'll have a big grin on friday :afro:

Post by: Hulmie on 15 July 2010, 17:47: i had a problem with the butterfly previously on mine as it was only part open on full throttle. just adjusted it and all was good, got the power back.

yours will be fine mate.
