throttle body troubles ph1 172

[Spongebob 172]

going to work this morning and i noticed that the revs would not drop below 2k..so i took the air filter off and had a little clean of the throttle body put it all back together but still no joy..i then thought maybe its the throttle cable that was sticking but thats all fine...any ideas what could be the problem,its on a ph1 172

Well known issue. Throttle body spring plays up.

how do i fix this warren???can it be fixed??

 

[ForceIndia]

New throttle body iirc

Sure its not getting air in between throttle body and plenum?

I had an air leak on the inlet manifold and it was ticking over at 5000 rpm.

It was the rubber o ring at the back not seated properly. Worth a look, afterall its free!

dont think so...ive just seen a guide on stripping the tb so i might have another go tomorrow as it could be the spindle and spring inside the tb...oh and a new one from renault is £257+vat so i wont be getting one of them

This happened to my TB tried the guide out made absolutly no difference.
Luckily whilst my car was in Ktec this week they got me a second hand one for £70.

just had this problem too. i hate it . its a bit better now after cleaning but if gets worse looks like it is the new tb

isn't the ph1 tb cable? if so, it is sticking open? you must be able to fix it?

This will be your problem, follow my guide and it WILL be fixed mate, iv done over 2000 miles now and mine is still perfect, before doing this no matter what i tried didnt fix it, you have to leave it to soak in properly though, best to leave it as long as you can, a good few hours at least

i did this today and it didnt do anything..i left the tb to soak in carb cleaner for 6 hours....

 

[sideways danny]

did you lubricate the spindle before re-fitting? cleaning it gets all the dirt out, but it also washes away any lubrication. A few squirts of WD40 or similar will help

What danny said, you need to fully re-lube the spring, and the edges of the spindle inside the body mate? iv found its very important to lube the spindle fully, otherwise the butterfly will still stick
