What for wires are this, going to the gazolin pump. There are 4, 2 fat and 2 small wires. (Ford Focus c-max 08/2005. I think: 2 for gazolin sensor (the smaller), 2 for pump (black and brown-green). but what is what?

Pin 1 - Signal (Green/Yellow) Pin 2 - Signal Return (Grey/Red) Pin 3 - Signal (Orange/Red) Pin 4 - +5V Reference (Orange/Yellow) Pin 5 - Ground (Black) Pin 6 - Not Used

I got this free Pdf man ual from reliable-store for free and I don't think Ive visited a mechanic or fixya for help for more than 3-4 times out of the 2 0 times I fixed the chipper in these 4 years

This can be caused by a defective Maf sensor and coolant sensor, they will not trigger a code because as long as there is a signal the computer doesn't know the actual engine running condition enough to say the signal from the 2 sensors is wrong, this goes double for MAF sensors, another area is the idle speed control motor.. I want you to read about the problem at the link below.

Ford MAX 2003 2010 03 1 8 Unstable Idle when slowing Technical matters...

On that system you have 3 ride height sensors. 2 front 1 rear. Disconnect the linkage arm and try to move sensor arm. Should move with little resistance but not loose. If bound up replace,also check 2 remaining sensors. Behind the passenger headlight is your compressor and relay. You can jump the 2 fat wires together at the relay to activate the compressor. The relay has 4 wires 2 fat 2 skinny. They sell a conversion kit to elinmate air ride and have coil struts and shocks. I normally recommend the conversion so the problem doesn't happen again. Nice system till it goes wrong

A pair of extractors are required (available from Ebay , Halfords or
email us for details ) but these can be made from 2 pieces of bent, wire
coat-hanger or 4 small drills(using the blunt end) or 4 small Allen Keys
or 4 small screwdrivers or 4 nails or even 4 darts.

An assistant is useful to pull the radio out whilst you are releasing the 4
securing clips

NOW THE COLORS ON THE VEHICAL ARE GOING TO BE DIFFERENT AND YOU WILL NEED A 12 VOLT TEST LIGHT FOR MAKEING SURE YOU HAVE THE WRITE WIRES FROM THE CAR TO THE TOE BAR, DON'T NEED BACK UP TIGHTS FOR THIS

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!

dont think so it could be the throttle sensor causeing the problem hope i have helped you
