After 2 days, mechanics were able to determine what caused my “Check Engine” light to come on: the ignition coils and spark plugs!!
I was able to get about $300 taken off the price of servicing my car!
Not as Good News:
That brought it down to $1000. Plus tax.
And I haven’t had steady work since May. When I quit. During a recession.
(Just in case that fact had been forgotten.)
