2000 ford escort 2.0L. plugs, wires, coil pack, alternator, MAF sensor. hard to start and RPM around 1k wants to die (any stops) always runs rough. Says air intake sensor. catalytic converter or CCRM?

Have you cleaned the throttle body and throttle body valve? have you cleaned the idle speed control air bypass valve? are the injectors clean? Are there any fault codes in memory, do the things I mentioned if you haven't already. Also hard engine mounts can cause roughness at idle. Another thing is the timing belt tight?

The alternator is grounded through the mounting bracket;

How much would it cost to fit a new alternator on a ford focus zetec 2001

If you can put it on your self, the alternator could run from anywhere from $100.00-150.00 for a new alternator. Call your local auto part store and check the prices. It would cost alot more to take it in.

Hi, I bought used Audi A6 Quattro 130K miles. For the first several days, it run without any problem. Early this month, I was driving a rather hilly highway and the car start to drive rough,hearing some...

I would check to see if the catalyic converter is clogged. Drop the tail pipe at the manifold. Start and drive it for a block you will be able to tell real quick. It should run smooth and have good power. It will just be noisy. Or you could have coil problems.

Battery Light is On

The alternator is not charging the battery. Could be alternator, voltage regulator (which is usually in the alternator) , dirty/loose connections. First I would inspect all relevant electrical connections, clean & tighten. If no change -- replace alternator.

But be sure to fully charge the battery before you run the new alternator (follow alternator installation instructions).

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!
