About a month ago, I was breaking for a stop sign and my '04 F150 stalled before I came to a complete stop. There was a "check gauges" message displayed. My husband checked the oil and noticed that it was low but still within the acceptable minimum-maximum range, so we took it to get an oil and oil filter change anyway. 3 weeks later, I started the truck and saw the same "check gauges" message again but it still started and functioned properly all day. Today, we used it in the morning and no problem, then we drove it 2 miles and it stalled when slowing down for a turn. The same message came on and we had some difficulty getting it started again. We took it to an auto parts to get the free diagnostic test but they could not tell us anything because the service engine light was not on. We were driving back home and it stalled again when slowing down for a stop light with the same "check gauges" message. We looked at the manual and it said that it might be one of these 3 things: coolant, oil pressure, or low fuel. We have a full tank, the battery is good, the temperature was normal and so was the oil gauge. PLEASE !!!!

Check to see if you have a crack in your oil cap (if you are sure that it is on tight). I had that light come on after changing my oil when I started the engine before installing the cap.

I checked and the cap is on tight...no cracks. But even if it did have any cracks I don't think that would be reason enough for my truck to stall.

If the truck sees a drop in crankcase pressure, it will stall the engine to "save" it.

ive had 3 things cause mine to stall like that. clogged fuel filter, throttle positioning sensor went out, and another time something broke off of the sending unit inside the fuel tank (but that was from driving fast on extremely rough roads). i have also been told that o2 sensors can cause it too but most likely it is just the filter or tp sensor. another possibility could be the mass air flow sensor. im sure there are several other things that could cause it but try having the fuel filter changed and if that doesnt fix it you can try some of the things i listed or take it to a shop and see if they can give you a definite answer for whats wrong.

Usually if it is the fuel filter it stalls more when going faster and there is more of a demand for fuel, the O2 sensor would be my call that will stall a vehicle a lower rpms but usually sets off the check engine. the tp sensor should cause a bit of a hunting in the engine if it is failing and also is connected to the check engine. This is what I have seen in the marine mechanics world. Your best bet is to get a handheld DTC or take to dealer so that the sensors can be read while functioning.

Also make sure that you check the specs on the inline for the rotary-durter.

I'm retarded.

mine never stalled at high rpms, it got to a point where it would buck a lot and i couldnt gain speed but in the beginning it did exactly what azil is describing at low rpm's. my engine light would come on sometimes and the codes i pulled referred to lean fuel/air mixture, stuck sensor bank 1 and 2, low fuel rail pressure. all the parts store guys and the dealership kept saying o2 sensors but i never did change them and my truck runs perfect now.

Here is a good example of when it's time to take the vehicle into a qualified shop for repair. You have recieved 3 possible (but not proven) suggestions, and you may still have a truck that stalls.

You did not mention the mileage on the truck. O2 sensors can begin to fail without setting an engine code, but usually an owner begins to complain of lower gas mileage, and/or black sooty tailpipe conditions. This may be related to your engine stall condition, but your truck has two inboard (before the catalitic converter) O2 sensors, and two outboard (after the calalitic converter) O2 sensors. This will set you back almost $200.00 for the sensors alone, not including labor (unless you change them yourself), and there is no garrantee this is the fix to your problem.

Rather then throw new parts (and a strong chance of wasted money) at the truck, take it in and get it diagnosed, and fixed.

These sites are great for getting suggestions on symptoms, but its only a forum to share ideas, fixes, and opinions. When several different parts suggestions are offered, it's time to take the truck in. The chances are good that one of above mentioned suggestions is correct; it's a crap shoot for you though to guess as to which one(s) you are going to do, and spend your money on.

Just trying to save you money.

Well, I couldn't get a free diagnose because the service engine light was not on, but the guy from the auto parts suggested that it could be a clogged fuel filter. My uncle basically does all repairs at low cost but might not have it ready asap, how much will it cost to have a service like this done?
