Finally got a new vacuum pump installed.
Got 20 hg of vac.
But car runs like poop.
Very low power, white smoke, burning smell.
Missing at idle.

Is my injection timing messed up?
Chain skip a tooth but not break?

Could it be serious engine damage.?
Should I get a compression test?

I drove for 20 minutes and it didn't get worse
Or better so I'm not sure it could be bad
Or clogged fuel
