You're bang on there buddy........it was certailnly not clean, but not ridculously dirrty, however as stated, i did clean it very thoroughly with carb cleaner, along with the ICV for good measure, it may have been something as silly as that you know.
How can one prevent that from occuring again, or is it something that should just be cleaned on a monthly basis.
Ypu say, "just about off on foot closed". Once i cleaned the TB, i couldnt see the other side, it was shite quite fully from what my eyes could see, should it be open more?
Sabs
Car refuses to start from cold....pls help

This fits the symptoms of a failing fuel pump i experienced once, and is one of the things that the two battery suggestion further up the page was intended to check out.siddiqi1 wrote: i went to start it. Firstly aftr the first turn it sprang into life,but only to immediately stall. After the 2nd turn it startd,spluttered ever so lightly and then went on idling perfectly!
The cars springs into life on the residual fuel pressure in the fuel rail, but the pump doesn't start because of the reduced cranking voltage, and the engine stalls. The second time you try to start it, the engine turns a little easier, because it's just run, the cranking voltage doesn't go quite so low, and the engine starts.
Once it's running, the pump gets over 13 volts, and gives no more trouble.
Wouldn't go tampering with the throttle setting at this stage, there are initial settings for throttle opening and the throttle closed limit switch etc. but on tickover with throttles closed, " foot off" they appear closed, but the primary butterfly will be just off the fully closed. The area to clean is the area around the butterflys with them held wide open, whats downstream in the inlet tracts isn't going to cause a problem. Just do one thing at a time, otherwise you can disturb all sorts of things that were OK, and introduce more faults. Mind the edges of the butterflys, they are very sharp and can slice your finger open.
Good luck.
Good luck.
