I have a 2003 Ford Taurus, when originally starting the car cold it starts and idles fine. Can drive about a mile or two and nothing seems to be wrong with the car. After that the car loses power and sometimes stalls. Battery light flickers for a second. First it was throwing the O2 sensors code but since then I have changed the fuel filter and fuel pump and the codes have not come back on but still the same problem. Thinking it may be the CAT, but been reading other forums saying it could be coils and plugs. Figured that would be throwing a code though. Any ideas???
Thanks
