Seized waxstat fast idler mechanism on back of pre-facelift TB (I usually remove the obsolete mechanism).
Plus also a sticky/seized idle control valve, at front of preface TB and at back of facelift Bosch TB.
Unscrew n remove the iacv, clean fully with carb or brake cleaner till valve moves smoothly.

Hi pollyp,
Thanks Agent_Sm1th,4 bolts 1 at each corner of throttle body. Unscrew them And lift off.
Hi pollyp,
I have tried to locate and open it, but unfortunately noticed that in order to open it tb has to be removed as can be seen here: .
Furthermore, the car thrown a p130 error code. Now can you please advise/instruct me how go about it?
Regards
Thanks pollyp,the TB has to be removed via those 4 star torx head bolts (the prefacelift uses allen heads) for easier access to the IACV screws
p130 is bad or out of range O2 sensor

Thanks pollyp,
Checked o2 sensor and its 0.5 or some times fluctuating up to 0.9 and 0.4.
Replaced the 02 sensor in 2013 and the car was standing since May 2013. Basically its done less then 2000 miles with the new sensor which is universal one!
Is it possible to clean an 02 sensor? If yes, what with?
I have not opened the iacv yet since haven't received the torx that ordered from Amazon yet.
Regards
Thanks pollyp,if the O2 is flicking up/down twice per sec at 2k rpm then it's responding fine. unless ur burning loadsa oil & soot, they rarely need cleaning (at worst could prob just brush the soot buildup off) since any residue usually burns/blows itself off.
best off cleaning and getting the IACV working first before considering any replacement of a more expensive O2 sensor.
Thanks pollyp,
I have noticed one of the spark leads is quit oily due to oil spillage perhaps. Was wondering if cleaning the spark connection will do any good. I have got contact cleaner will it any harm/good if sprayed on the electrical connection in general and spark connection in particular?
This is the product I gothttp://www.amazon.co.uk/gp/aw/d/B003IIGVBS/ref=mp_s_a_1_17?qid=1449310638&sr=8-17&pi=SL75&keywords=contact+cleaner+electrical
Please advise.

Thanks pollypif ur gonna replace coolant, drain it all before unplugging the TB lines will make it abit easier so dont have to bung the pipes.
remember to turn heater dial full hot to open the matrix pipes to drain & bleed.
just spray through the TB mesh aimed at the maf wire
Thanks pollyp,Turn to hot for both draining cold coolant and when bleeding system with running engine.
Thanks pollyp,yep thats the bosch IACV removed and is a sealed unit. just need to spray carb/brake cleaner into both openings to clean/flush any carbon/dirt off the moving valve ports inside and reinstall.
check for any vac leaks
Thank polly,look at the video.
the TB gasket is a thin plastic that doesn't normally leak unless u intentionally wreck it.
Thanks davyboy,Its the old throttle body problem - surely???
Do the old solder trick, of stick a new TB on.
