Same here, more zip ties with every repair - now the "injector rail" is tied to fuel rail and the FPS connector (with broken clip) is tied to FPS. Today I retested all wires using multimeter (wiggled the crap out of them) but no dice. Not sure how to interpret results. It's quite likely that the harness is put together from wires that are soldered somewhere in the middle (wire colors don't match on both ends) - really bad idea as solder joint can break, corrode and start acting up (more so as the engine bay warms up). I still don't want to rip it apart (tomorrow I test drive it to work after applying these additional zip ties). Also bad thing is that I could not find replacement at the junkyard - bunch of Focuses but all had different connector (main harness plug) even though the engine was the same (Zetec).

The car started misfiring badly again and I decided to drop it off at another mechanic. They ran diagnostics and returned 5 faults:

PO171 Too Lean
PO202 Injector Circuit Fault
PO300 Random Misfire
PO302 #2 Misfire
PO316 Misfire On Startup

They said many connectors were not on tightly and the mechanic also repaired one wire on the injector harness with a splice. I drove twenty miles home and it feels like a new car.

He also did front rotors and brakes and replaced the back tires which were scalloped and making a thumping noise, of which I have had my fill of...

So 725.00 later and my Focus is rolling new and hope is restored. I do love this car. If it keeps going smooth, I see a body-kit and paint job coming in late summer.

That's exactly why I brought it to the large non-dealer service center that I did. I considered the Ford dealer but hoped to get a free-thinker and good mechanic. Besides they had aligned the car and put on front tires and a battery when I bought this car last year.

I have much hope the problem will not return but only time will tell. I'm taking tomorrow off so a nice cruise with the windows down will be in order.

Glad you got everything straightened out, and hopefully the issues stay away!

Well, no joy!

On the way to work the engine light started blinking and the engine misfiring. Drove it to the same mechanic, they looked at it everything they had done, pulled a misfire fault from the computer, disconnected and reconnected something, started the car and it ran fine...

ARGGGGG!!!!!!!!!!

Said it must be a short and they didn't didn't know if it would take them 1 hour or 10 hours to find it so I picked it up and will leave it with the mechanics I bought it from who do claim they will stand behind the car and get it fixed. I doubt it, too many gremlins in this vehicle. Another one popped up today. When I press the lock button on the key-fob twice, the horn would usually beep, now, no beep.

This will not end well. I can feel it.

Took it back to the guys I bought it from. They had it three days and when I picked it up he said he couldn't find anything but tied down the wiring harness real good...

I told him he didn't fix anything and the problem will be back.

Drove home a mile and then had to move the car, when I started it the radio station had changed to AM 550, all static, I didn't put it there...

Drove 4 miles to get gas and car started to misfire baldly, engine light flashing...

Car going back to mechanic Monday morning. Says he will change injectors because the one that is on the engine now is from the old engine and he has the newer one from the 2009 engine.

I'm beginning to think the car is junk and can not be fixed. Even if I pick up a 700 dollar used 2005 engine and replace the main wiring harness, I am not sure I catch the problem. If I knew that would put the problem to rest, I'd drop another 1,000 on this car just to be done with problem.

I'm sorry I bought this particular car because all signs pointed me to walk on it but I trusted the guy I bought it from. Still love the Focus itself, just this one is a real bitch.

Got the Focus back today. He changed the injectors, I will find out exactly what in a couple days but evidently we had a 2005 wiring harness hooked to 2009 injector connector and the connection was not exactly sound. Similar to what the other service station said, "lots of loose connections" so maybe he found the problem. He kept the car for a day so he could drive it from time to time, put about 35 miles on it. I drove it only 5 miles today but it seemed to run very well and the rough idle was gone. He also changed plugs.

Hopefully it will work this time!

I talked to the mechanic today and he's not sure if the injectors he changed were 2005 or 2009. I think they are 2005 but the important thing is you can now move the wires all you want and you can't induce a misfire or sputter. Problem solved, wrong injector connections.


The OTHER PROBLEM has NOT gone away. yesterday while driving home the radio starting getting very load, the high-beam indicator started flashing rapidly and the relay was clicking as well. While this was going on, the engine began to sputter. Lasted less than 10 seconds and no CEL.

I have googled some info on that and it may be a faulty alternator. I will be looking into that.
