The only way to tell if you have a ring or valve problem is to do the compression test as it the best place to start . Once you have eliminated the compression from the equation then you can concentrate on why the cylinder is getting more fuel than the others. I would be checking for vacuum leaks for the rough running as an incorrect fuel / air ratio will cause missing. We cannot fix everything but we endeavour to point you in the right direction so that you can fix it.
Well the code means the computer detected a drop in RPM for that cylinder. The problem can be spark, fuel, or compression. If you think the cylinder is getting spark, the other two causes would need to be checked.
Are you saying the engine will not crank, or not start ? If you think two of the cylinders are not getting spark, something may have happened to the coil pack or the crank-cam sensors. If all 4 plug wires are getting spark, two of them may be on the wrong cylinders. The firing order is not always the same as the plug wire layout.
If you replaced the distributor cap then there is a high possibility that you put the wires in the wrong firing order on cap.
If all you did was replaced the plugs, then I would pull each one out and recheck the Gap sizes with a feeler gauge. Also check to see if the spark/coil plug wires are touching metal or each other, which can cause the spark to arc out of the wire and never get to the spark plug. If I suspect an arc and do not see a physical problem, I wait until nighttime and look under the hood while engine is running...they stick out like a sore thumb. Also make sure that you did not put the wrong plugwire to the wrong spark plug.
When you change your plugs, you should also replace wires, cap and rotor.
If the vac. line went to the distributer cap you need to get a new 1 take off the line and take it to the auto parts store and get a new 1. What that vac. line does is adjust the timing when you give the car gas. Did he make shur to gap the plugs to the wright gap? If he did and you put a new vac. line on check all of the vac. line if they have cracks change them. If the still runs ruff he might have moved the distributer, or he might have got the wires wrong if he changed the spark plug wires. Change the vac. lines first they are cheap.
