check my thread titled ZX3tunrs focus problems
What year i syour focus. If its older then 2003 check and see if you had the fuel pump recall.
If you changed the plugs and wires then it ccould be MAF or DPFE.
Do the DPFE tests and see if your DPFE is gone. During the test if your car drives better then you know its the DPFE.
