Check spark plug wires

99 camry 160,000 miles origional spark plugs.

I'm going to replace them.

I want to check spark plug wires beforehand to see if need relaced.

I have digial vom.

In old days after dark you could start motor, raise hood and look for
arcing.

Nowadays the headlights come on automatically.

Any way to temp disable headlights to allow visual inspection ?

The plug wires should have no more than 25K-ohm per foot. Pull the Head
light relay (or the two 15A head lamp fuses) to disable the lamps.

You can replace them on a preventative basis, but unless there are
breaks you can still use them at 160Kmiles.

thanks for the reply.

i get 20 mpg around town.

does this sound right?

I don't go on trips

i think I'll just pull the easy 3 front plugs and see how they look.

I changed all 6 on another v6 3.0 camry and it took like 4 hours for
the back three.

Dont play games , replace them, have you ever checked the rotor or caps
carbon tracking, im sure not, replace them. Have you ever checked
timing, I bet not, You will get 3-5 mpg better when you learn to care
for your car.

That's a bold claim. I have never had that kind of reward for replacing
anything except parts which made a car run noticeably badly, sometimes not
then. Especially these days when ignition components are less critical than
they used to be.

adjustment a quarter turn and the computer turns it back a quarter turn.

The shotgun approach -- replace everything in hopes that it will fix
something is not very sophisticated and is certainly not economical. If
your car doesn't run right, diagnose it and repair what is broken.

On many cars, pulling the parking brake up to the first click will
disable the auto headlight feature.

The computer does nopt over ride timing adjustments, it uses them as a
baseline. Thinking the computer does is ignorant of its operation.

Timing is also much less likely to have wandered out of adjustment than on
older cars.

I tried pulling up on hand brake.

lights still turn off & on with ignition
