black spark plugs 1800 1972

posted by  someone claiming to be cross country on  Sun Sep 7 14:55 CST 2003 [RELATED]

Hello

I seem to have an over rich gas mixture and am wondering how to proceed. At times, she backfires at lower speeds but seems to clear out on the highway. I am wondering if it is more likely to be the air sensor, temp sensor, or pressure sensor. I am assuming the problem is not the injector(s)


any help would be appreciated.

thanks
