hard to start. cranks over for about 30sec or more
What is your question?
when I start the car it takes a long time to actually start. It seems like up to a minute, although I did not time the duration. When it starts the motor is a rough idol. I recently replaced my plugs and wires, but this did not change the situation. A mechanic suggested turning the car on and off and on a few times to prime the fuel line, but this hasnt seemed to make a change. When it is running it runs fine on the road and at stop lights it idols smooth.

The fuel pressure regulator on this car is a very common source of this problem. The single-cylinder misfires may be related to this, but not necessarily. Make sure that the cam angle adjuster is not leaking oil that would drip down around the plugs: if there's any oil around the plugs in the plug wells, you'll have misfires soon after the engine starts.
