Just from some personal experiences i've been going thru:

My car has been running like sh*t for a long time now and i've been replacing all these parts that didn't really need to be replaced but i did it trying to look for a solution.

My best advice is Regular Maintenance:
Air filter (even if you think its clean inspect it)
Oil
Fuel Filter
Fluids
And ignition (Spark plugs,Cap, Rotor, Wires, Coil)etc. etc.

In my case i've negelected my ignition rotor since i've had my car That was about 50,000 miles ago

Now my car runs better than any performance part i've put on.

 

how much was the rotor?

 

$10 bucks i just went to autozone.

 

can you give the symptoms...I've been wondering about that distro on mine. 148K and its the original to me

 

I didnt know the ignition rotor needed servicing/replacement... very curious

more info please.

 

its always good to do tuneups. that should be the first thing on your list.

 

The rotor/cap should be a part of your regular tuneup. Every 45k or 60k, according to the manual if I remember right?

You can take off your cap and make sure the terminals are still clean and in good condition.

And the orig poster is absolutely right...maintenance is KEY.
