If you ran the MC dry, you may have sucked in a ton of air. If you're sure the system is now completely sealed you have to just keep pumping and bleeding, preferably starting at the right rear brake, then to the left rear brake, the right front and finally the left front. Sometimes no matter how much you pump the air will not come out, then you have to use a mighty VAC and power bleed the system.
Hi I am a tech mechanic I deal with things like that Evey day lol but sounds like the anti theft or the ignition switch n lock n key to but you also have broke wires touching even in thecolom
Check these three things in the misfiring cylinder: spark, gas, and compression. One of them is wrong or missing. For spark check the spark plug and wire. Make sure you have spark on the plug wire, a strong blue spark. For gas, the fuel/air mixture may be wrong. Does the fuel injector pulse, putting gas into the cylinder? Possibly you may have a leaking injector or a clogged injector.If gas and spark seem okay, you need to check compression in the cylinder. Low compression will cause a misfire. If compression is 20 or 25% lower than adjacent cylinders, that could be causing a misfire. For example, say numbers 1 and 3 cylinders had about 150 psi compression. 80% of 150 = 120, so if cylinder 2 is 120psi or less, that could be setting the misfire code. Low compression can be caused by valves not seating well, or bad piston rings, bad head gasket- something in the combustion area of the cylinder is losing compression.
It may just be a coil breaking down or a bad spark plug. Try swapping one of the coils over with the faulty one and see if the misfire happens on that cylinder and cylinder 2 runs fine. If it does then swap the faulty one for a new coil. Don't know about your car but most now have individual coils for each cylinder that fit directly onto each spark plug.
Check for power with a test light with the light connected. If you have power then its the ground. If no power then you will need to trace the wire back to find break. As I recall they did have seperate fuse for left and right headlight high & low beam. Also did you get a defective new bulb?
Did you check for OBD Codes?
Did you have a shop drive it with scanner,
& see if all the Emission Monitors have run?
Ever do any Preventative Maintenance, or just
drive your vehicles until you have problems !
Did you check for fuel pressure at the motor & spark ?
Battery Dead or worn out !
No one can guess at your vehicle issues-- without it-- to
do some testing,always been that way
