Learn how to diagnose and repair engine misfires without engine code...

at least try changing number 4 cylinder spark plug and wire, see if it makes a difference.
good luck !

Sounds like you have a bad bcm as far as the lights ! The running rough and the cel flashing indicates a misfire condition ! Check your plug wires and see if a critter hasnt chewed a wire !

yes if it is loose can cause a misfire replace the wires as a set

I would perform a compression test on all cylinders if you've already changed your plugs and wires. This willtell u if u have ay mechanical problems with the engine. Also even tho you've changed your spark plugs and wires did you check your injectors or coil packs to ensure they're good. A problem with either will also cause misfires.

Running rough and misfiring is usually a one or more bad spark plug wires. Don't go back to that dealer. Replace the wires or have your mechanic do it for you. If you replace them, take one off at a time and install the new one. If you put the wires back on in the wrong order, it will misfire.

Next change swap the injector with another and see of the problem moves.  If it does it's a bad injector.  

Have the injecter checked, could be faulty, also check and see if you have spark at that plug wire.

ignition mod. grounds,pcm or timing belt could all be it but, I would have to look at timing first.

It sounds as thou you have moisture in your distributor.Pull the distributor cap off and let the car sit and dry out for a couple of days and see if that fixes the problem.
