    Yes I bought the 21lb. injectors because Ford changed from 19 to 21 during the 2002 year and I thought it may help my lean issue. I got them off e-bay and maybe they have been causing me issues ever since. I have had them about two years. I always run at least two fuel filters and have never had to change one due to drivability issues. I don't understand what has happened. I did not really think they would get dirty running good filters.

    Jerry if I'm not mistaken the switch to 21# injectors coincided with a fuel pressure change, but don't quote me.
