Will try that on Sunday, thanks. Will also try the dreaded butane gas method!

But you may want to seal the wires better just to keep dust out. Have you tried blocking off the main TB inlet (right at the TB) to see if you can stall the engine that way? If you can then the TB butterfly is simply not closing properly. ----- Original Message ----- From: "Frank Smyth" <[EMAIL PROTECTED]> To: "Ray Ayala" <[EMAIL PROTECTED]> Cc: "Miatapower" <[email protected]> Sent: Saturday, September 27, 2008 12:34 PM Subject: RE: Obiwan not idling properly With the BOV's vacuum signal blocked, IDLE% still goes down to 15%, but *very* slowly With the BOV hooked up, it drops to 15% quite quickly. It's sucking air through its filter when idling. Is this by design ? I found that the rubber pipe in which the temperature sender is wired is also leaking a bit. I'll have to find a better way of situating those wires. -----Original Message----- From: Ray Ayala [mailto:[EMAIL PROTECTED] Sent: 27 September 2008 20:08 To: Frank Smyth Cc: Miatapower Subject: Re: Obiwan not idling properly It should not allow air into the vacuum supply hose as that will contribute to the idle problem. Does the IDLE% rise when the vacuum supply hose is disconnected and plugged? If so the BOV piston (or sleeve) may be worn out. ----- Original Message ----- From: "Frank Smyth" <[EMAIL PROTECTED]> To: <[email protected]> Sent: Saturday, September 27, 2008 11:42 AM Subject: RE: Obiwan not idling properly > Fitted new injector parts and the idle is now down from 1100rpm to 950rpm, > IDLE% still drops to 15%. > > The BOV (FM aluminium version) hisses like mad when the car is idling - > should this be letting air in at idle ?
