I did a compression test this weekend since I changed out the plugs that came in the car. I put in a set of NGK V-Powers. I have always had good results with NGK's in my DSM's so I used them in the Camry as well. Anyway here were my results..

190-190-190-192

I don't know what the tolerance is on the 5S-FE but I would assume these are good numbers. I don't have a factory service manual yet so can someone tell me what is says about where it should be at? Thanks,

i'd say those are some pretty strong numbers

wht items did you need to run the compression test? I'm gonna have to do it in the next week or two.

a compression gauge... pull the wires off the rest of the spark plugs so the car won't start and crank for a couple of seconds

What you want to do is remove all the spark plug wires from the plugs. Then remove ALL 4 plugs. In the fuse box under the hood remove the EFI FUSE. Use a good quality compression tester that holds the max pressure. Screw the compression tester into the plug hole and make sure it is sealed well. Crank the engine over 6 times while pressing the accelerator to the floor. Check the psi reading. Check each cylinder.

I borrowed it from a friend a long time ago. He ended up giving it to me.
