Stop and think for a minute. In the old days, problems could fester and develop into major disasters without warning. If the problem didn't happen to make a loud noise, you simply didn't know about it. That check engine light, (connected to a f***in' computer) let you know that something was wrong. It could be any number of things. Would you prefer the indicator known as "Stranded in the middle of nowhere late at night in a thunderstorm"? You can safely bet that a tow truck will charge you more than $69 just to show up.
So then you go to the dealer, who DOES FIND AND FIX a problem. (stuck wiring, whatever that is - most wires are there dfor a reason, and that one might have been capable of burning up a wiring harness or worse) Without that "f***in' computer" the mechanic might have spent many hours trying to track down an intermittent problem. The bill would have been considerably higher than $69. Maybe 10 times that amount.
In other words, you should be very thankful for "f***in' computers" and especially thankful for that incredibly measly repair bill.
