No, there is no coil or Spark Plugs. Ignition takes place due to heating from compression of the fuel/air mixture. Some diesel engines have a "Glow Plug" for aid to starting in very cold weather.

1992 Saturn runs good when cold misses when warm?
This issue could be due to a faulty ignition coil, spark plugs, or fuel injectors. When the engine is warm, these components may struggle to function properly, causing the misfiring. Have a mechanic inspect and potentially replace these parts to resolve the issue.
How do you change the spark plugs in 1997 mark viii?
Take the intake tube off the intake plenum/mass air flow sensor box and put it out of the way. Then remove the two bolts that hold the plate on top of the valve cover off which will expose the coil packs. Unplug the coil packs very carefully and then gently pull straight up on each coil and the plugs will be exposed. ou will need a 10" extension to reach all the way down in the tube to get the plugs out. BE VERY CAREFUL HERE AND ONLY DO THIS WHEN THE ENGINE IS COLD, DO NOT DO IT WHEN THE ENGINE IS EVEN SLIGHTLY WARM, COLD, COLD, COLD! You SHOULD replace the spark plug boots when you replace the spark plugs. The boots are the rubber parts that are attached to the coil packs that cover the the top of the spark plugs. This should be done as the extreme conditions these rubber part endure cause them to weaken and when they are pulled out they sometimes get a small pinhole in them and then the spark is sent out the pinhole to the spark plug tube and you will have a rough idle, low performance and likely a check engine light. When reinstalling the coil packs press them down firmly and sort of "wiggle" them down till they are seated firmly on the plug. Use an ANTI-SEIZE on the spark plugs so that they will not get stuck in the heads which will cause expensive damage to the headss the next time you want to replace the plugs. Carefully clean the top of the valve covers where the plates that go over the coil packs come into contact with the valve covers and make sure that the gaskets on the plates are clean and still pliable....The rear of each plate has a half round opening to allow the wire harness for the coil packs to come through. Pay close attention to this area upon reinstallation so that they seal properly around the wire harnesses.
Have a idle problem with a 98 windstar 3.8idles good when cold idles rough and stalls when warm works fine when driving?

Peugeot 306 s16 when cold take a long time to start then once its going it idles to low and sounds like its running on 3 cylinders when its warm its fine?
Check connections on the coil packs, the cover can sometimes interfere with the wiring. If not check spark plugs and connections from the coil packs to the plugs, the plugs are situated underneath the cover which has 16V cast on to it (the rear cover) the other cover is a camshaft cover. Failing that it could possibly be an ecu problem.

What would be wrong with a 1993 Chevy Corsica if it runs rough when its cold and runs better when its warm?
Likely needs a tune up. Replace all spark plugs, plug wires, distributor cap (if it has one) and air filter. If it still runs rough you will have to go to a mechanic.
