Vehicle stalls continuously, but only when the outside temp is above 50 degrees. I've replaced cadil. converters, fuel filter, air filter, and all oxygen sensors. Service engine light is not on. What am I missing that is causing this problem.

    Stalling when coming to a stop sign - deceleration stall? If so you may have a low engine idle caused by a dirty throttle body. If cleaning the throttle body does not help you may need to scan the engine computer data and look for a sensor that is out spec enough to cause a proplem but not far enough to turn on the service engine soon light. Does the engine stall after it warms up when the outside temp is below 50 degrees?

    Check the wiring harness pins at the fuel pump coming out of the tank, i found that the pump pins where burnt out causing the pump to cut out. a new harness cost me about 40. bucks. good luck
