my check engine light came on the other day and the codes came up as random miss in all cylinders. the car has 60k miles so i did a tune up (plugs, wires, cap, rotor,and air filter) the check engine light came back on with the same codes. is there any known problem that can cause a the check engine light to come on like this? could i change the coils? someone told me that the use of anti-size on the threads and dielectric grease on the contacts of the plugs can cause a bad contact and maybe even a miss, is the true?

Thanks.
