Nate,
Never heard of this, but I would like to hear the details on the instruction
sheet.

Hey all, just wanted to know if anyones had this
problem! A buddy of mine drives a '97 4X4 Auto. He
took it in for emmisions insp. last week and failed
miserably! The only mod he's done is a drop in K&N
filter. They asked him if he'd disconnected the
battery anytime in the near past and yes he had (can't
remember why.) They told him that more than likely
the computer had dumped some settings when he did this
and that's why it wouldn't pass. They gave him a
little instruction sheet that led him through a series
of steps he had to perform while running his truck to
make his puter "relearn" some emissions settings.
Something like start it with AC on, run at a certain
RPM in N for 1 minute, drive at a certain speed for a
certain amount of time, accelerate WOT to a certain
speed, etc... etc... (He's got the instruction sheet
at home and is gonna give me a copy if anyones
interested.) He went out on the road, did what the
sheet said, came back and they retested his emissions.
 He passed with flying colers! Anybody been through
this? Seemed kinda wierd to me!
