Compression test

[7:34pm]

Haven't done one yet on the Yaris yet but feel the need to now. Is it just remove the fuel pump fuse, remove spark plugs, depress throttle and crank?

This is what I got. From left to right across the board. Wanted to do a wet test as well but didn't have any oil or squirter bottle. My theory why the two end ones are lower is because they were a bit cooler, being on the outside... thoughts?

Temperature would not make that big of a difference. The tolerable limit is 14 psi between cylinders, so you are OK.
