A "Haynes Manual" on your car would help, but will not tell you compression values. A rule of thumb, is about 150 psi per cylinder...which doesn't really mean anything. What you need to do is remove all the spark plugs, have someone push the accelerator pedal all the way to the floor and spin the engine over four times. Record the first reading (the first turn-over) and the last. Do the rest of the cylinders the same way. THEN, squirt 20 ml of oil in each cylinder and re-do the test (this oil seals the piston rings), and the pressure will increase a bit. Then compare the readings and if two adjacent cylinders are low, then the problem will lay in that area. A very High Compression reading could mean a heavily carboned combustion area, but the exact compression reading varies, even in new cars coming off the factory line.
Good Luck,
