Rough idle & stalling at a stop

This maybe due to a dirty Idle Air control valve or a throttle position sensor. YouTube can provide good answers for removal and testing of the Throttle Positon Sensor (TPS) as well as cleaning the Idle Air Control Valve (IAC)

My idle is low on my 2001 ford focus se and it is a stick shift so my car dies when I come to a stop unless I have my foot on the gas just a bit. how can I turn up the idle? Help please.

The idle is computer controlled. It takes a reading from the crankshaft position sensor as well as the camshaft position sensor along with basic information from other sensors, processes it and sends a pulse signal to the intake air control valve (IAC). The IAC valve is positioned to allow air to bypass the throttle plate and control the idle. Once the throttle is opened the IAC is commanded on 100% until the throttle is closed. In short, a scan of the pids needs to be done to determine whether the processor is commanding the IAC on properly or if the IAC just isn't responding properly.

A scan for codes can be done but many times an IAC won't throw a code so the sensor pids really need to be performed to determine the root cause.Good luck.

2001 ford focus zx3 temperature gauge goes in the red and the yellow exclimation comes on. But all coolant levels are ok and no leaks and the fans run.

the problem may be the temperature sensor or the gauge itself, it is most likely easier to replace the sensor than the gauge....hope this helps.......cheers

Ford focus idling bad

I recently bought a used 2001 zx3 with 130k miles:
1. Ran rough as a cob. Ford has a "Safety Campaign" (not a recall) on the fuel sending unit/fuel pump. Had mine replaced for FREE at the dealer. You do NOT have to be the original owner. BUT, this is only a 10 year window on the replacement (10 years from original purchase). I squeeked in by only 4 months. Afterward car ran much better, but still sickly under 1500 rpms.
2. Replaced the fuel filter (1 hour job) and spark plugs (30 min). Fuel filter was so full of garbage it felt like somebody had put a dead rat in it before sealing it up. Plugs were fouled too. Ran even better but AC was still lukewarm at around 500 rpm (where it wants to idle at).
3. Going to clean, not replace, idle control valve. This is a tricky one because of its location- on the intake manifold next to the throttle housing. I know folks are going to scream at me about cleaning it and not replacing but it runs about $50-$150 depending on the supplier. I've read a how to on one of the focus enthusiast sites and looks like a 30 min job. Counting the can of WD-40 I already have this should cost me $0.
Good luck!

Rough idle and engine will shut off after warm.

Check the exhaust manifold gasket. I have a 2003 SVT Focus I had a problem with it loping at low RPMs. I had a free flow exhaust system. When I bought a new exhaust manifold I replaced the gasket and the problem went away.
