Random misfires are also caused by faulty injectors
the fault code reading is the first step to saving money and fixing the fault.
On your stratus you can get the codes by turning your key on and off 6 or 7 times I can't quite remember but they will show up where your odometer is
Get the OBD codes read this will tell you which switch/sensor is causing the issue , the last random misfire i encountered turned out to be low cylinder compression so if the OBD code says " random misfire " then get the cylinder compressions read , hope this helps
If the compression is off on those cylinders, would that indicate a head gasket issue?
could be the gasket or a few other things , poor valve seats , cracked head , piston rings ,if the cylinder compression/s are low you can try a leak down test , follow this linkhttps://www.youtube.com/watch?v=WgrfT0LF... keep me posted

Bad coil
A six cylinder coil is three coils in one 1&3 work off one coil segment my guess is that is bad

A multi misfire may mean that one or more of the following has happened:
Faulty spark plug or wires, Faulty coil (pack), Faulty oxygen sensor(s), Faulty fuel injector(s), Stuck/blocked EGR valve / passages, Faulty camshaft position sensor, Defective computer.
The engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wire, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the the problems were faulty fuel injectors.
Random misfires that jump around from one cylinder to another (read: P030x codes) also will set a P0300 code. The underlying cause is often a lean fuel condition, which may be due to a vacuum leak in the intake manifold or unmetered air getting past the airflow sensor, or an EGR valve that is stuck open.
Good luck and hope this information helps, keep me posted, be glad to help you get the truck running 100% again. Not sure if your running a K&N air filter, and if you are there may be a flim of oil on the MAF sensor that is making you run lean. You may want to spray down the MAF sensor with a can of MAF cleaner.

try a new crankshaft sensor not hard to change 2 bolts and a wire

did you check to verify that you have the wires in the correct order possible distributor pick up bad

when u press the gas pedal to go this opens the throttle valve, the idle speed of your engine is computer controlled, this is done by the ISC (idle speed control) airbypass valve, these parts get full of gunk and then get a stalling problem at or near idle, clean them by doing the following, if u don't understand the instructions seek help from your friend.
, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

Hi.
The check engine light, driving problems and smell was in consequence of the misfires. If now the car drives fine, the vacuum leak could have been the cause of the original troubles. As far as I understood now the problem is only when idle.
Ensure that you have replaced the air filter , also double check vacuum and check/clean the air intake duct and sensors (IAT, MAP- see here for removal). Those are factors that can affect and cause misfire during idle. The IAC valve can also cause similar troubles and must be checked.
All the part listed above may cause lean or rich mixture. The problem is not necessarily detected by the O2 sensors in the exhaust and may result in no lean or rich code being stored in ECM.
If mixture and air intake are not responsible, and if the problem does not only occurr when idle, check the high voltage wires from coils to spark plugs (particularly if a code on a particular cylinder comes back). Check timing, valves, EGR and fuel pressure/fuel pump. Try doing an injector cleaning and check injectors (both spray and voltage).
