#2957 of 2996 Rough Idle when cold
by nomoreford2
Jan 11, 2011 (8:44 pm)
I have a 2000 Taurus with a 24V DOHC and got a P0171 & P0174 error codes about running lean. The car runs rough cold - rpm goes 2,00 then down to 500 then stalls out - 3 or 4 times im 10 minutes. after it gets warm its ok and runs 700-800 rpm when idle. I cleaned EGR value, replaced PCV, changed air filter, I checked for vacum leaks - didn't notice any and still getting code. Previously i got a 1506 Idle over speed error and replaced Idle Air control and it came back but went away with the PCV replacement, but now i will get the P171 P174 sometimes. Any ideas to what maybe causing this. This problem seemed to get worse when firestone put 5W20 oil in the car on the last oil change instead of the usual 5w30 the car has always used.
#2958 of 2996 2000 Taurus power steering

I have a 2000 Taurus with 101,000 miles on it and the power steering went. I replaced the pump and it still has no power steering! It’s a little better turning to the right but not much. I don’t think it’s the rack, the wheel isn’t binding up or sloppy it’s just a complete upper body workout to turn it. If anyone has any suggestions I would appreciate it.

I have the same problem with my 2001 Mercury Sable LS. It started back about 5 months ago. I would start the car with no problems. The car would go thru about a 2 min cycle on a higher idle and then when it was over the rpms would drop down to 500 like yours does. It would act like there was no gas and jerk or lunge causing lights to dim and brighten because the engine was surging on and off. Finally it seemed like the computer figured out a problem and would increase gas and the rpms would go back up. The check engine light didn't appear for a couple of weeks. When it did it showed the infamous P0171 & P0174 bank 1 and 2 lean. I replaced the Mass Air Flow sensor and it did nothing. Then I saw a posting on another site about the PCV valve elbow where it goes into the intake manifold. The elbow is smooth rubber and collapses causing vacuum problems. Sure enough mine was totally collapsed. The part was only 25.00 at the Ford Dealership and I had it put on. It actually seemed better for a while. I thought that would be the end of it. But about 1 week after the codes reappeared and the same symptoms as well. All this time since it started back 5 months ago I've had horrible gas mileage. I wish there was a way to check the whole vacuum system for problems because that is where seems to still be after reading tons of postings. I'm not sure if it is in the intake manifold gasket itself or some vacuum line. I'm frustrated and very leery of replacing 02 sensors because it seems unlikely that they are both bad at the same time. Let me know if you find anything out. Thanks

I bought some electronic cleaner and sprayed the Mass Air Flow sensor down, and the connections to that and the throttle position sensor and the rough idle went down big time, but is still slightly there when cold. If your still getting that code, you can try to spray your EGR and Idle air control with some air intake cleaner. If that doesnt fix it the only only things could image would be the DPFE sensor or fuel pressure regulator and if that doesnt fix it its time for a trade in.

After posting my problem on another site I took their advice and took it to a repair garage that had a smoke machine. They found that the intake manifold gasket was leaking causing too much air being sucked in. If the two codes P0171 and P0174 (bank #1 and #2 Lean) then it most definitely a vacuum problem. I actually had two vacuum problems. The pcv elbow was collapsed and the intake manifold gasket needed replaced. I had them replace the other vacuum lines when they had it apart because my car has 146,000 miles and the rubber is old. Now my car runs awesome with no lean codes. No more choking out when engine is cold. After the initial idle when the tach drops down I am no longer getting a bad fuel to air mixture that used to make the car lunge and the lights flicker because there wasn't enough fuel to make up the difference of the air intake and it was all after the Mass Air Sensor. Hope this helps someone.
#2962 of 2996 Alarm goes off whenever I open the door

My 2003 Sable scared the crap out of my dog (literally). When this happened I fumbled around for a while trying to figure out what to do. I stumbled onto the idea that the key fob has a panic button - so I pressed that - nothing. I pressed it again and mercifully the racket stopped. Did I mention I was in my garage at the time? I think I may be going deaf, my ears are still ringing. After cleaning up the dog mess I experimented a little and found that this seems to happen no matter which door I open - but fortunately I can stop it right away by two presses of the panic button.
We have been having a very cold and snowy winter so I'm suspecting some ice (or ice melt) may be causing the problem. My garage is unheated and last time I checked, the thermometer was at 12 F. Any suggestions what to look at or do next? (short of driving to the dealer).
Thanks.

2001 Ford Taurus check eng light on with a DTC P0402.This happens about every 2.5 years and I replace the Backpressure sensor and that will take care of it. Is this normal on this year? We brought it new and now has 58,000 + miles (wife car) I have had 2 other Taurus a 1996 with over 200,000 miles and a 2003 with 170,000 miles and have never replace that part. Purchase the part at Advance Auto Parts should I get Ford parts?

It's your battery terminals. I had the same problem. Change those and you will have no problem.

These posts were helpful thx
What I did was to jack up the back as high as I could with the floor jack with the tire still on then I put some 2x8 scrap wood 3 pcs stacked up under the tire so the right rear would settle securely, then lowered the jack and with about 6" of wood only under one tire the spring was compressed enough to easely pop the old one off and plenty of room to work with the new one.
#2966 of 2996 2004 Taurus Accelerator Sticking

My accelerator is sticking on my 2004 Taurus. Sometimes I'll let my foot off the gas and the RPMs will still be over 2000. It really worries me at times, especially when I'm in traffic or at a stop light. It doesn't do it all the time, but has been happening more often. Any thoughts?
