    Really need to carefully inspect all of your tune up parts i.e. wires, plugs, car, rotor as well as your fuel filter and air filter. I never let these go for more than 30k and the air filter I replace every year.

    Thanks for your prompt reply. I put new plugs in. the cap all 4 contacts were really corroded up i had to scrap the white hard carbon off them it did run better. Maybe the cap needs replacing otherwise it sits and idles nicely. the rpms flictuate up and down a bit but thats all.
