My girlfriends '02 ford focus 2.0l dohc has been missing for a while and i cant figure out whats wrong with it. It only misses in between 2k-3k rpms and only under heavy throttle or going up a steep hill. Check engine light indicated misfire in cylinder #4. I have replaced the spark plugs (properly gapped) , spark plug wires, air filter, fuel filter, and fuel injector for cylinder #4. the car idels great and cruises just fine.could this be a fuel pump issue. Also, i have checked all vaccum hoses and all check out. I am lost please help.... indicate any and all things in could possibly be.
