So my car was stalling and backfiring when I would start it up. I took it to 2 different mechanics who couldn't figure out the problem so I took it into the dealership where I bought it and found out that my warranty was void. I left it with them for a week and they wound up finding a lot of stuff wrong (or so they said). I paid $960 for them to replace a bunch of stuff. I got it home and it did the exact same thing it backfired and died. So I searched my butt off, looking for posts on here with the same problem and found out that it could just be the regulator in my alternator. I took my alternator to a shop had them check it out and sure enough that was the problem. A $60 fix that turned out to be $1020



Thank you OxFordGt and Jmac72187

That sucks but at least you figured it out. I know how you feel. What was replaced by Ford?

 

they replaced the spark plugs, 2 Hegos (i don't know what those are), reflashed my pcm, and put on some mil's

 

LOL That's it? WTF are Hegos? I really hope you took some vasoline in there to make that a$$ rape go a little easier when you paid the bill.

 

i looked it up and hegos are just another name for o2 sensors... yeah it sucked pretty bad payin that... by the way black35 your car sounds good man

 

Wow, I learned something new lol. I've never heard o2 sensors called hego's. That really sucks man, I guess you live and you learn. You should throw a rock through one of the new cars windows thats sitting on thier lot, it would probably make you feel better anyways lol.

Thanks for the compliment on the exhaust man.

 

LMFAO!! ahaha

 

HEGOS = Heated Exhaust Gas Oxygen Sensor, that's what they are called in the factory manuals.

To the OP, I doubt very much they "put on some mil's" in what is the classic meaning of "MILs" (MIL eliminators) in the forums--that would be a violation of Federal law which could cause them to lose their dealership. Most likely the "cleared MILs".

In any event $960 for the work they did makes MY butthole hurt, and they did it to you--must be one of those sympathetic pains....

 

Man this sucks, it kinda happend to me but somethin different, and i didnt get screwed as bad as you, but i had a hole in my exhaust so i took it to this shop to fix it, and they did but in the process they unplugged all my spark plugs, so we paid for my exhaust was bout to leave and i started my car and it started shakin and my engine was knockin, and the guy was like ooo you got bad engine, i was like no, it didnt do this before, and he was tryin to tell me all this dumba** sh*t that was wrong, so me and my daddy were tryin to figure it out for a while, we did so much stuff, then finally he bout all new sprak plugs and come to find out that dumba** switched my spark plugs up!! then after we fixed it, it ran perfect!! WTF, mechanics be tryin to screw everybody
