i've got a terrible miss, but it's only part of the time. it will run fine most of the time and then every now and then it will just start acting like its not getting fire... it just runs really rough and gets jumpy and then it will all the sudden kick in. i heard if moisture gets in the distributor it will act like this? idk ya'll tell me!

 

well start with the simple things. 1 codes 2 plug wires 3 plugs 4 codes 5 opti cap and rotor.

 

^ This. Check the codes. Sounds like it's possible that you've got a wire contacting a header/manifold, or the opti encoder could be going wacky. Start with the basics and go from there.

 

well i guess i should have added that i already changed plugs and wires, as far as pulling the codes goes, it's giving me trouble i tried shorting it out where it plugs in like they told me to do at the parts house and it didnt work..
