I will check the compression tomorrow.

No other codes
Cam shaft retard at -18 will give you many problems.
Including miss fires and burned cap and rotor and to hot of ing spark.
At -18 it is firing 18 degrees from plug wire terminal.
Wide gap for spark to jump.

If dist is set right.

And if a locked solid dist plate.
The dist gear may need turned 190 degrees to make it come out right.
Or hold down plate slotted some.
It needs to be at -0 or as close as you can get it.
