check spark plug wires

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.

I tried pulling up on hand brake.

no go

lights still turn off & on with ignition

20 on a V6 is probably OK.

4 hours for rear bank plugs is a bit long. You should be able to reach
all plugs from the driver side, using no more than either 3" or 6"
extension (yes, just one at a time) with a spark plug socket and a
standard 3/8" ratchet. No need for u-joints on the extensions. You may
prefer to remove the PCV valve and hose from the manifold instead of
getting the right most plug from the driver side. Shouldn't take you
more than 30 minutes. The fronts ones I'd say no more than 5 minutes or
10 if you work slooow

The timing belt does stretch with time reducing mileage and increase
emissions. If you do your own work I'd say change it (and the pump,
pulleys, seals) at 60K miles. 90K miles is a bit long.

Belts stretch mine was 3-4 degrees off, its a common issue over looked
thats hurts power and mpg.

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

Today's timing belts do not use steel cords. They are types of kevlar
cords. Toyota had years of problems with the 5SFE belt stretching to
the point of slapping the timing cover until they updated the belt
around 2001(?). So timing belts can strech and they can strech baaaad.

There are of course other cord materials, like the Gates' carbon cord
composit belt developed for Harley Davidson. Hardley wanted to put a
wider wheel on their bikes, and instead of using metal chains Gates was
asked to come up with the world's first commercially successful
"carbon cord elastomeric composite belt". It's a thin belt with the
strength of metal chains.

While some belts are spec'ed to go over 100,000 miles (like the Gates
timing belts in Hondas), I do my own work and would change them out at
60,000 miles. $30 for a big rubber band is cheap (plus other usual
parts for a timing job of course).

I have a preference for Gates Timing Component Kits. They include the
idler and tensioner pulleys. www.gates.com

That's almost a belt tooth - if it has stretched that much (and they have
steel wire inside), you should worry about the belt not the timing.
