I have a 2004 ford f150 5.4 triton when I take off from park it sometimes stalls and it sometimes has a surging no power, it also has the no power surging takeing off from a stop sign or light at times. This could happens two days in a row and not happen for two weeks again, I've took it in and no codes come up and it never seems to do it when the garage has it, any ideas ?

sounds like the torque converter lock up might not be disengaging. You might also want to check for engine vacuum leaks. Does engine idle smoothly when in park or nuetral ? if the idle is good I would suspect torque converter problem.

Follow this procedure for these kinds of problems.


Here is the most common cause of surges and stalls and low idle, it is the idle speed control air-bypass valve and throttle valve, they get full of gunk over the miles and cause idle issues (stalls) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

these vehicles have a problem with the torque converters locking up after a long drive. this will cause it to stall when coming to a stop. Do you feel a shuddering when stopping?

replace the accalerator pump in the carbrator this is located at the bottom of carb. or front above fuel filter! this should cure the hiccups and problem.

it could also be the idle control valve not working properly, it could be carboned up, remove and clean with a cloth then replace and try car
