Replaces ams air flo sensor, replaced rubber boots on air intake not fixed yet ant help please
Normally cause by air in the fuel pump. Check for fuel leaks on shafts.at filters, Check for proper tank ventilation. have the fuel pump checked for internal governor pressure.

Change the plugs and the rotor insode the distributor. Sounds like your focus has either a hole in the Rotor Button, a cracked rotor button or the plugs need to be changed. Anotehr thing that would make your focus stall, **** and generally be a pain in the **** is: Fuel injectors out of hole; bad fuel injector; bad gasoline; Air filters need changing.
Those are basically some of the things that cause the Focus to jump and ****.

have you cleaned the throttle plate? this is done by removing air intake hose and spraying out with cleaner and wiping it down open throttle and wipe off the butterfly and bore. this will usually cure a stumble.

Check ontop of the transmission bell housing. I believe there's an orange wire going to it.

Hi. From your symptoms I would guess a fuel issue. These engines are sensitive when it comes to engine oil quality. There are quite a few things to consider. Take a look at the oil first. Is the oil full, does it feel deluded or smell like diesel? Are the oil changes performed on time? Are both fuel filters changed every second or third oil change? Does the engine run perfect at low speeds but poorly at high speeds? if so, look at fuel filters and pump pressure. Pay attention to the pressure information. Even if the fuel pump pressure passes don't stop yet. Take it for a drive with the tester attached and run the truck until the symptoms appear. Does the fuel pressure deteriorate? If so, this could be a failure inside the fuel tank (Clogged screens). Fuel pump pressure should be between 45-50 PSI. Why don't you start there. Please let me know how diagnostics is going and if you need more information. I always encourage people to be descriptive. The more information the better. Good Luck.
