Yesterday my car started to misfire pretty badly on the way home. I have new spark plugs(autolite resistor plugs, really cheap plugs). My plug wires are maybe two years old. I pulled them to check the resistance and all met specs at about 6k ohms resistance. On two of the plugs the boot at the end of the wire where it connects onto the plug is gone because they tore when taking wires off awhile ago. My fuel filter is maybe 1 1/2 years old. I have no error codes.
With all that being said, the car will misfire horrible at idle, if i give it gas it usually stops about 2k rpm and occasionally will take until 3k prm before it stops misfiring. Than when i let off the gas it will misfire again as soon as the rpms drop. Any ideas??

When was the last time you replaced your distributor cap & rotor? And did you have a lot of moisture (rain, snow, etc..) in the air prior to this symptom? Check the distributor cap for cracks as well as electrode condition. Make sure there is no moisture inside the cap either. In the online shop manual you will find further procedures for testing various ignition related components. Best of luck.
