Car Stalling out at idle non-stop!

[JayTye4k]

Hello all, I have a 95XLT and it is stalling out on me everytime I come to a stop. The idle starts sputtering and it sounds like I'm out of gas. Here is a list of things I've already fixed:

1. New IAC Valve
2. Fuel Filter
3. New Plugs & Wires
4. New Air Filter
5. Cleaned MAF
6. Seafoam intake
7. Seafoam in gastank
8. New Coolant Tempeture valve
9. Checked for air leaks-nothing

I would hate to take it to the stealership and I've done all of the above myself. Anyone that can be of help would REALLY be appreciated!!

Have you reset the computer after doing all that? That might be all it needs. Disconnect the battery cables for 30 minutes and see what that does. good luck.

I left the battery unplugged overnight and I'm still having the issue. Could this be my fuel pump or fuel injectors???

Heeeeeeeeelp!!!!!

Does it do it after you are stopped and you have restarted the engine? Will the engine keep going if you put your foot lightly on the gas? If it only happens when comingto a stop it could be the torque converter clutch not unlocking. This could be the result of your brake switch not working.

Also your brake booster could be bad.Mine did that and it was the fuelpump.it would drop to 10-15 psi,when it should stay at 35-45psi.

Any idea what this would cost in repair?

Sounds to me like the EGR valve is stuck open.

Sounds to me like the EGR valve is stuck open.

Now why didn't I think of that? try tapping it with a hammer lightly.or put a vacuum gun on it and open ad close it, or remove it and cleane it out.

I'm going to put the information you sent me in an email so everyone can see it, then I'll try to help with what I can.

I have a 1995 Ford Explorer XLT. Lately I have been getting
a rough idle when in gear, at a stop. The engine is even occasionally dying due
to the low idle. I have replaced the plugs, wires, fuel filter, cleaned MAF,
replaced IAC to no avail. I do not see any vaccuum leaks up top either.
WHen the idle starts dropping, it sounds/feels as if it is either a)getting too
much fuel, or b) not getting the right mixture, or enough fuel.
Interestingly, when I turn on the air conditioner, it idles fine. Does this
sound like a failing oxygen sensor? Any way that I can turn up the idle?

I'm not getting any codes at all. Any help on this would be greatly appreciated.

Your symptoms match in many ways my symptoms when I had a bad O2 sensor, except that I also had an O2 sensor code both in continuous memory and during the KOER test.
When you say you're "not getting any codes at all" does that really mean no codes at all, or does it mean all pass codes?
Your gut instinct has suggested that it might be either too much fuel or too little fuel. If I were in your shoes, I'd hook up a fuel pressure gauge and run a few tests to see if the correct amount of fuel is getting to the fuel rail. It may not catch all failure modes for the FPR (see Opera Houses many posts mentioning a sticky FPR valve), but it will catch most. One common failure mode for the FPR can be checked simply by pulling the vacuum line off of the FPR after running the engine. If there's gas in that vacuum line, the FPR is bad (ruptured diaphragm).
Your note reagarding it running better with the AC on is interesting. Not sure what it means, but the computer monitors the AC switch and adjusts the idle up when it detects that the AC is on. Might suggest that it's a simple matter of a dirty IAC valve and/or the passageways in the upper intake that feed air to the IAC valve.
I would also agree that your symptoms could be caused by an EGR fault. I would expect an EGR fault to set an EGR code, but EEC-IV is kind of funny. It can miss problems on occasion.
