Really too much to guess about, but here's my guess:
Is the check engine light (CEL) on? You probably would have mentioned
it if it was on, but have the codes read even if the CEL is not on. As
to your plugs and wires...did you use Motorcraft plug wires and
Motorcraft or Autolite plugs? Those are the only brands I would use in
a Ford. The plug wires are more expensive, but worth it. Did you ever
replace your fuel filter? From there, I would look at he O2 sensor and
the MAF. After that, it's a big reach, but fuel injectors would be on
the list also. |

Air filter, fuel filter and clean the thermistor in the MAF. >> Stay informed about: Stumbles under Load |
