We've had our '92 LS400 since it was two years old. Very reliable car. Last
year one of the two ignition coils went out. Since the other one was just as
old, I suggested to the (independent) tech. that maybe it would be wise to
replace the other one, too. He consulted with the Lexus parts counter guy
who told him that they seldom go out in pairs. The other one may last
another decade. So, only one was replaced.

Last week the fuel pump went out and I had the same shop fix it. They fixed
it promptly and just as they were pulling out of the garage bay, the
computer threw a code. The code said the other coil was failing.

Sigh.

Short moral is that if you lose one coil, you might as well change the other
at the same time.

The total cost for the two coils plus the fuel pump will be about $1,000.

Double sigh.
