[ARC5] Environment - unexplained effects.

Sun Aug 24 20:22:04 EDT 2014

Chris Your memory of the column is better than mine.  I agree with your recollection but I am unable to add to it.

I suppose the following story is off topic.  Apologies offered in advance.  But it does seem to fit the general theme of unexplained events---- that sometimes have entirely ordinary explanations:

True story. Happened in Mercer, PA. 

A guy takes his Ford F-250 pickup to the service 
department at the dealer where he bought it.
He tells them that the temp gauge is running 
against the peg and the performance is bizarre.
They tell him it isn't blowing any trouble codes 
on the computer. The truck is fine. It's probably
the temp gauge.

Unconvinced, he takes it to another Ford dealer
in Grove City. Same answer. Take two aspirin. 
Get some sleep. The problem will go away.

Takes it to some old guy with white hair. The old
guy starts it up. Revs it a few times. Walks in front
of the truck. Pops the hood. Sticks his head under 
the hood and listens. Never plugged in a computer.

Turns to the owner and says "You let your wife drive
this didn't you?"

"Yeah, last night", the guy replies. "But how can you tell
that from listening to the engine?"

"Because you have a tank full of mostly gasoline" the
old guy says. "Lucky for you there was still a good 
amount of diesel in the tank when she gassed up.
Otherwise, you wouldn't even be able to get it to start." 

Nobody thought to put a code in the computer for bad 
fuel. And, if the computer says everything is fine, then 
everything is fine.

True story.

What was the name of that monthly feature?  I remember it was about a guy maybe named Gus who had to diagnose weird car problems like you described...the name of the feature might have included the name of the garage.  I used to read it all the time, some if my first lessons in troubleshooting.  I'm also remembering a similar monthly feature one of the electronics mags, maybe Popular Electronics that was about a radio and TV repair shop where they had to deal with oddball electronics troubleshooting challenges.

> Leslie's comment reminded me of this story.  When I was a kid mechanics Illustrated magazine had an auto repair advice column.  There was a man who had a problem with his car refusing to start but only when he stopped on the way home from work to buy ice cream and only when he bough butter brickle ice cream.  He never had a problem when he bought vanilla or chocolate.
