Can throttle sensor cause misfire?

If there are no misfire codes, a commoncause of acceleration stumble is a bad throttleposition sensor (TPS). The computer uses this information todetermine how much fuel is needed to maintain the correct air/fuelmixture and when extra fuel is needed if the throttlesuddenly opens wide.
