No lead on the plugs, as Jay pointed out, so it's not due to plug fouling.

In my case, the fouling was on valve seats.

How would a fouled plug kill compression? G

ok how would a fouled plug kill compression....

If its fouled.. it isn't burning all the fuel that is being injected
into the cylinder and thus your compression is actually forcing that
out the exhaust thus lowering compression because its not pushing the
cylinder all the way do BDC so your not getting the full potential out
of your cyliner or engine with the plugs are fouled.
