Re: V6-no idle

Hi Pat,

I've been away for a couple of days, so sorry if this has been answered 
before.

You've damaged the switch inside the AirFlow Meter.  There is a switch 
inside that activates when the vane opens.  The backfire will have 
slammed the vane closed and must have damaged the switch.  If you're 
brave enough, you can pull the black cover off the AFM (requires removal 
of the adhesive that sticks it to the metal part) and when you look 
inside at the top RHS of the assembly is a small set of contacts, I 
suspect that with the vane in a position other than that of closed, 
those contacts won't close.  Bend them until they do.  They should 
reopen when the vane closes (engine off).  There are many pictures of 
the l-jet AFM on th web.

If you can't be stuffed with ll that fussing around, just get a good 
secondhand one.  PLug and Play after that.

Cheers
Stuart
