1992 Ford f-150 stalling. Happens after cold

Have the catalytic converter checked at your local muffler shop...clogged...worn out...Hope this helps.

SOUND LIKE FUEL PUMP FAILING OR STOPPED UP FUEL FILTER, CHECK FOR FUEL PRESSURE SEE IF YOU HAVE FUEL PRESSURE, IF YES PROBLEM COULD BE EGR VALVE STUCK OPEN WHICH WILL CAUSE CHECK ENGINE LIGHT TO FLASH.

sounds to me that there could be an engine temperature switch that is malfunctioning or not working at all. the temperature switch tells the engine that its cold and that the fuel injection system should operate in cold mode. the switch then tells the computer to start the engine in cold mode. if it malfunctions, the engine controlling unit confuses itself and then cuts off. this is an early sign of that unit failing until the car won't start at all. it's just wear and tear and time that does these things. a good mechanic should help you out quick and should be a couple of ours work. good luck

SCAN IT CHECK.FOR A FAULTY FUEL PUMP OR RELAY.

Go to Autozone or Oreillys for a free scan. It could be the TPS(throttle position sensor) but the scan will identify the problem.

Sounds like a cold start valve (which is actually an additional injector in the intake to assist in cold starting) If you can get it to your local prts store while the light is on they will read the codes for free and tell you what the car thinks is amiss.

I had this problem also and it turned out to be related to the cold start system. cant remember the part name but it was causing the hesitation problem.

These re known for head gasket failures when at operating temp. should do a compression check hot and cold.

You need to clean the throttle body and idle air bypass valve with spray carb cleaner, hold the idle high while you do this as the engine will try to stall, disconnect battery when done for 5 minutes then reconnect and drive a few days to relearn idle strategy.

The ford dealership has my truck now, they said it was the injectors leaking and not holding gas in the fuel rail for start up, and that would also fix the sputtering problem i have. I will know for sure no later than wensday 2/4/09 if that fixes the problem. I will post the results when i get my truck back
