Ive been having this problem on and off for months now, just today it got real bad. I can go start the car and the rpms will go up then all the way down and die or it might rev back up on its own and stay running. It takes about 3-10 times to get the escape started and keep it running. It doesnt matter if i put it in park or drive and hit the gas or brake, it dies either way if it wants with no pattern at all. It has 114,000 miles and is a 2003 escape v6, has newer plugs oil change and a brand new tranny. Ive been looking to trade it in for months now and starting to regret not trading it in with a blown transmisson for $2,500.

If this matters at all it just started to happen again after i filled it up with shell gas, I would say bad gas but that would mean i get bad like 40% of the time i get gas from all diff stations.

I would start with the usual suspects, e.g. MAF, IAC, TB cleanings. I assume there's no codes showing up since you didn't mention it. Perhaps disconnect the PCV valve to see if it makes a difference. Replacing it is a little more involved. Just pop one of the lines leading from it off. Hope this gets you somewhere.

I was having the same problem as per Leo's advise to replace the iac that is what solved my problem and man i can relate to what your saying about trading it in. I have been looking at used escapes for the last week or so But went to the dealer yesterday to get the iac valve and the price of the new escape are real good. I think we may get a new one problem now is the wife wants the new one for her and she wants me to start driving her escape. (we have 2 2002 escapes and love these trucks )

Did you check the Throttle Position Sensor? I was also going to suggest fuel pump before I read the part about revving back up on its way to dying out... Fuel pump would explain the dying, but not the revving. That points me more toward TPS, or like the others were saying, maybe the IAC. I dont recall anyone spelling that out....in case you dont know, Idle Air Control motor.
