Question about 2003 Ford Focus

3 Answers

My 2003 Ford Focus ZX5 check engine light came on. The car idles fine and cruises fine but when the engine is loaded (throttle cracked open) it bucks and spits and sputters. I've changed the MAF meter which helped some but I need to know what else might be wrong.

Have you hooked this up to an OBD11 reader yet ?
May be a bad crank, cam or knock sensor. Cars today are loaded with sensors.
If you don't read the codes you will be chasing the rabbit down the hole. ;-)
Hope this helps

How many miles on the car? Have you ever changed the fuel filter? (Sounds like fuel pump and filter)

    Take it to Auto Zone and have them scan it and get the code. It could be a few things causing your problem. Need the code.

2004 Ford Focus ZX5 - car skips beats/rhythm while idling. Random w/ no set pattern.


can be a few ideas: check plug wires, misfiring, check the plug, if you dont have plugs, than check the [ where the plug should be]
it could be the timing belt slipping, in the 1970 we had timing chains that would last for every, but some one got idea is to put a belt in so at 60-70 thousand miles you need to replace timing belt.

there is no fuse for that, you would either have to fix the issue for the reason the light is on or disconnect the battery for a few hours to erase the memory in the cars computer.

Have a 2003 ford focus. idling problem


if you have 14 volts or more at the battery at 1000 rpms, the battery & alternator are fine. If you get the same surge when you turn the bower motor on high speed, it is just the normal load on the alternator as it puts out more current. The engine is supposed to compensate by kicking up the idle. It does this through the IAC, idle air control. You may need to clean the IAC passages and the throttle body passages. I also would clean the MAF sensor heated wires with carb cleaner or MAF sensor cleaner. The MAF is in the iar intake hose and has a 2 or 3 wire connector going to it. The heated wires are in the air stream. Then disconnect the battery for 2 hours to clear the "Keep alive memory"
It will relearn after you drive for 10 miles. May run rough for that time.
good luck.

My 2003 ford focus started his morning but as soon as I removed my foot from the accelerator my car would die. This happened numerous times this morning.


Your idle control valve is either dirty or bad. You should be getting a check engine light on your dash.
The idle control valve is located on your throttle body.
If you have a check engine light on you will need to plug a OBD II reader in to retrieve the code.
Please let me know what you find.

2003ford taurus bucks at cruising speed 30 to50


Sounds like your mass air flow sensor....or your intake air temperature sensor. Have the vehicle DTC codes checked....Youo may not have a check engine light but a fault code could be stored in the ECM computer. Most auto parts stores will check it for free.

You can't beat free!!!

My car did the same thing with no check engine light and I changed the intake air temp sensor and it fix the problem right away.
