I will get a new set of spark plug wires and see if that helps, thanks

I forgot to mention that when i replaced the pcv i took off the oil filler cap and there was no vacuum

Is your coolant going down?

coolant is good

So, the pcv valve fixed the vacuum issue. Does it run exactly the same? With a P0300 there should be at least two other misfire codes with it. Be nice to know which cylinders are doing the misfiring.

The scan tool i used from oreillys only gave me the p0300, i asked if it could give me a specific cylinder and they said that the car was too old for the scan tool to give me any cylinder, I will start with new spark plug wires, I think it could also be one of the coils or the ICM

yes the car runs the same

That'* a bunch of crap.

found website called easyautodiagnostics.com, I went through the step by step procedure that was outlined and it was the ignition control module was bad, got a new one from NAPA and we are on the road again, thank you for all your help
