Change the coils they should be two black blocks on top of the engine..the coils could have gone bad.
you are not getting spark. this could be from a bad alternator, bad spark plugs, bad spark plug wires, or bad engine coils. The spark plugs and wires are the cheapest so try putting in new ones of those first.
bad crank shaft position sensor
Could be several things...It could be low on refridgerant or the coils could be dirty. Check the coils first as this is something you can do your self.
Check the crank position sensor
When the engine light comes on and the car shakes at the same time, it could be the spark plugs or ignition coils are faulty. Misfiring is causing the car to shake.
check the coils .they might be bad I'd try plugs/wires and fuel filter first. If it backfires when revved up while running rough, probably a spark problem, plugs, wires, or coils. But could also be a fuel problem (filter or water in gas).
No spark? No fuel?
Rust on the fly wheel and or coil.
possibily its the wrong plugs could be hitting the pistons
wrong spark plug wire configuration. Check to see if two are backwards.
I really hate to be the one to tell you the bad news but it is possible that you have bent some valves. Take the spark plugs out of the missing cylinders and run a compression check on those two.
the coil is bad
Wrong gap, wrong plug, poor groound when you are looking at the spark,
Could be a bad spark plug or spark plug wire. Time for a good tune up.
only two things left in the system are the ecm and the wiring... check for power on all circuits before replacing the ecm...
Out of time, or spark plug wires installed on wrong plug.
Could be a result from a bad spark plug(s), spark plug wire(s), distributor cap or rotor.
it could be weak spark plugs.
Does it have fuel/spark/compression?
It could be the timing belt jumps (wrong timing spark) or the faulty pressure regulator (to much fuel ro to little)
1. Tour timing could be off. 2. Low compression. Check gaskets. 3. Wrong spark plug type. 4. Bad coils. 5. Fuel-air mixture is not right. 6. Other prolems, e.g. bad leads, choke/enrichment problems, etc. Unless you know how to trouble shoot engines, I suggest to take it to a shop. 1. Tour timing could be off. 2. Low compression.

Timing belt may have jumped.
Could be that the threads are stripped on the plug or the head where the plug is screwed in. Or maybe it's the wrong plug..
