#463 of 490 '05 Focus with "System too lean" code
Mar 31, 2012 (8:38 am)
I have a recently wrecked '05 focus zx5. While putting it back together, I noticed that part of the air intake had come loose. I re attached it and tightened the hose clamp. Since then, the check engine light has been coming on. The code says "system too lean". I have run a tank of premium fuel, and put a bottle of Lucas fuel treatment in, but when I clear the code, the light comes back on in just a few miles. Any thoughts?

I wonder if you dislodged a vacuum line somewhere?

I will check. Things are so tight in there, and I know just enough to get myself in trouble!

Well I was thinking that if there was no engine light before you messed with the air intake and now there is, that a loose vacuum line would do that.
#467 of 490 2006 Focus low-beam headlight failure
Jul 26, 2012 (6:05 pm)
I have a 2006 Ford Focus. Both of my low-beam headlights are non-functioning. My hi-beams are fine. The focus bulbs incorporate both hi- and low-beams in the same bulb. I have swapped out both bulbs, the 20A low-beam fuse, both 10A (l & r) low-beam fuses, the 7A fuse, and the low-beam relay. None of these steps has resolved the problem. Anyone have any further suggestions?

Well that pretty much leaves the multi-function switch on the steering column I guess....or some bad wiring/loose connector somewhere.

my girlfriend has a 2001 ford focus wagon SE 2.0L we were having troubles with keeping the battery charged so we went to canadian tire and got it tested. Failed. We bought a new one now were having the same problem i think its the alternator. the symptoms are we will be driving and the lights will go off and the check engine light will come on also the airbag light.
then the car will putt and sputter then die, then the ticking and it wont start again. massive loss of power.
what should i do???
i checked the wires on the back of the alternator they seemed fine, ill check again in the morning.
the big red wire that's connected to the battery was loose and frayed so i cut it and hooked it up better. i gave the car a boost and same thing. lights, dash, and dummy gauges will flip all the way up then back to 0.
please help we don't have much money and replacing the alternator 5,6,7 times will kill us like the story's Ive been reading about.
also there's a humming sound my girlfriend says "It sounds like a RC car accelerating" it sounds like its coming from the passenger side under the hood, sometimes you can hear it threw the stereo.

I posted on this thread some time back, had the same issue with my 2003 Ford Focus. But if my car was in the middle of flashing dash lights on and off and I turned the car off, it never turned back on. So, I traveled with jumper cables and when it was in the middle of this chaos, I just drove it until it stopped (because once it started didn't mean it wouldn't stop at some point), especially if I didn't want to be stranded somewhere. We replaced batteries, alternators, had the post factory alarm system removed, changed the ignition...no avail. Even Ford Mechanics could not figure it out. Finally, a mechanic found that there was a "ground" loose and created a new ground for it. Initially, that seemed like the fix, we went a good 4 months without issues, however, at some point, the issue came back. We drove this car for 3 years with this issue, never was able to fix it. We called her Christine and just dealt with it until we were in a place to buy a new car. I was so happy when we sold that car!

That's funny, Christine is my girlfriend...
we just took out the alternator and it was extremely loose like the brushes were done, we didnt have time to put the new one in tonight but it should be a hour or so to put everything back in place hopefully she starts! and runs properly! also i think i have to do the aliment on the rear end. when im on the high way and hit a pot hole it the rear end swerves all over the place. i changed a lower control arm ( dog bone) and the sway bar linkage kit.
i didnt know it was a 4 wheel alignment. does anyone know if that is the problem or is it a sway bar problem?
