RE: Bucking 4KCSQ Resets Clock!?

["Buchholz, Steven" <Steven.Buchholz@kla-tencor.com>]

The clock is the biggest clue ... the ECU is losing power for some reason.
I'll bet you'll find that the fuse in the box that looks like a spare is now
blown.  There issems to be a fairly high frequency of this happening ... I
think Ken Keith was the first one I heard about in detail.  The power supply
for the ECU also goes to the WOT & Idle switches on the throttle body
(blk/blu if memory serves) ... and I think it even goes elsewhere.  What I
think is happening is that the insulation on this wire is wearing away at
some point and allowing the wire to short to ground ... blowing the fuse
eventually ...

HTH!
