changed plugs, wires, cap, rotor, even changed fpr and fuel filter and car still has funny idle. Seems lost of power a little bit. The idle does not go up and down, it holds steady rpm just choppy idle. I hope someone can help. Thanks

 

Check ignition and cam timing. Check valve clearances, and test spark. Also test fuel pressure and do a PCV valve test (pinch the vacuum hose of the PCV valve and listen for a "click." Is the problem temperature dependent?

 

PVC valve? Also timing

 

A compression test would rule out engine issues in short order. Give it a try.
