. It keeps dying when you press te clutch in coming to a stop. The exhaust tone is off a little. Idles fine when cold. When it warms up the idle get worse sounds like a mis in the idle from time to time. I found a broken vaccum line replaced it. Found another line pinched off that goes from behind the Tb into the passenger fender well. It throw 6 codes mainly o2 sensor upstream and lean codes. cel never came on... Guess next steps are replacing coil packs, o2 sensors, and that line. That not even looking into why it's smoking so bad.. One thing after another. Any other thoughts.

what color is the smoke? "smoking so bad" is never a sign of anything good in the motor.

loss of compression? rings?seals?

My car developed a miss so I proceeded to change coil packs/wires/fuel filter/plugs because they needed done. Anyway found that several plug holes had bad grommets and had a bunch of oil in them causing the misfire, so just ordered valve cover gasket set from felpro to fix it. Something for you to look at.
