Question about 2000 Ford Focus
VERY ROUGH IDLE ,PUT IT IN GEAR AND IT WANTS TO DIE . HAS CODES OF P1400 AND P1401. IF YOU CAN IT ROLLING ITS VERY BOGGY TO GET UP TO SPEED.
This is a hard one with out looking at the vehicle, but I give it a try. The two codes you have are for deferential pressure electronic low voltage and high voltage. First thing that I would do is check your connection on your MAF sensor, mass air flow located left side of eng compartment behind battery. Then I would check if the sensor is working proper. Please let me know if this works. I will be thinking about this one to see if there is something else.
