Hi all,
I am also new here and hope that this post is 1) relavent, and 2) in the proper place. Anywho....

I just acquired my grand daughter's 2006 Taurus SE 3L Vulcan. It had been sitting up for four months with a completely dead battery. I disconnected the batt. and hooked it up to a deep charger for 1.5 hr.s and added 3 gallons of fresh fuel (with a little fuel treatment to suck up any water, and rocked the car to try to mix old and new fuel). Upon restart the engine would rev to about 1.5K rpm.s and then slowly go to zero...
Restart with foot lightly on the gas pedal kept it running. Once yo to operating temp, it would idle roughly on it's own, but stay running. Yes, I got the 'Check Engine" light also. Managed to drive it home without issue. Spent two or three days computer reset and fuel mix re-learn procedures without success.

Finally, while checking out other issues and doing regular clean-up, I was checking the 'High Current Fuse panel' under the hood. I noticed two 'missing' fuses oone was a 20A ABS module valv solenoid and the other was a 10A A/C clutch relay/PCM Keep alive. It seems grand son had 'borrowed' a 5A alternator fuse, sicce the car was just sitting there and nobody was using it......

Well, the only 5A is something for the PCV and the Alternator is a 10A...... gonna have to teach the boy to read, or kill him.

Put a 20A in the ABS slot and a 10A in the PCM Keep Alive/ A/C clutch slot and guess what? Turn the key and the engine fires up and idles at about 1.5k for 30 seconds or so then drops to 900 to 1k. Purs like a kitten runs like a scalded dog... and the A/C works great now too!

New problem, Transaxle fluid leak at the pan??? Ah! found TSB 06-18-13 which says it might be the vent! makes sense since the car has been sitting up in the country for four months,,, have to check it out.

Whoever changed the transmission fluid last didn't torque the bolts enough, or they discarded the reuseable rubber gasket and put a cheap leaky cork one on there. I wonder if they used the correct (Mercon 5) fluid? Sounds like somone messed around with that car that didn't know what they were doing. I don't think that Taurus has abs, mine's a sel and it dosen't have abs, but there's an empty fuse slot for it. I would drop the trans pan and do the filter and replace pan gasket if it's not a rubber one, you can find the how-to in the wiki, FYI these transmissions seem to do better with full synthetic atf, like Mobil 1 atf. I had a transmission shop do mine, I brought my own (Mobil 1) atf with me. It cost $50 with my own fluid. The shop was off Slaughter, just east of Manchaca rd, right on Swanson Ranch rd, they'll look at it for free.
