O2 Sensor problems of the 2005 Ford Focus

So idk every [xxx] year! for the last few years! it goes good then she starts acting funny boom battery light comes on. I use the voltmeter and everything's fine full charge same with the alternator. A week or so passed then the starter went out replaced 7/3/13!! wtf! fried put a new one in. Now my[xxx] clutch feels different don't know what it's not slipping but it's really smooth. 2 days go by and boom acts like the battery is dead. . Nope take key out get voltmeter it's at 12. 5 so I try again seems ok doesn't turn over. Again turn key all lights on seems ok nothing. . . . Ok 1 more turn key struggles like starter then lights flicker dash wacks out boom dead nothing!!!!! get out still 12. 5volts. I don't know try 1 more time I pumped the clutch ad it hesitated to turn over and boom it works!!!! get home. Turn it off all is well acts like nothing is wrong! 4 to 6 days again this time it did it 2 him just different. Here's the kicker!!!!! it's fine fully charged all lights ok all volts ok he pulls out ( ha ha pulls out!) then she idles irregularly like a loop higher loop get it home and keeps looping. So I remember this from like 5 yrs ago it was something with the maf or ecg I believe so I look for answers. . . . Now he goes out 4 hrs later nothing dead won't turn over won't do nothing!!!!! I hate this car!!!!! I swear I will find the [xxx] problem to this [xxx]!!!!! I can't believe this [xxx] car! she was so good now she's a lil [xxx]! I know it's something stupid as [xxx] and watch just like last year in August the [xxx[ clutch is going to go out again! I loved this car but from reading constantly I've decided this is a serious Ford issue!!!! I have spent thousands on this! if I didn't have lifetime warranties on the alternator etc I could only imagine the cost!! through all this horror I've also had to replace O2 sensors maf sensor all engine mounts 3 times!!! information redacted pursuant to the freedom of information act (foia), 5 u.
