#45 of 54 rough idle by oldfordmech Sep 05, 2009 (4:34 pm)
Take a can of spray carb cleaner and with eng running, spray w/nozzle pointed at each intake manifolf runner where it bolts to the cyl head. If eng RPM raise or starts to idle normally, you found your leak. Look at your vacumn label by radiator and try to locate each line and check that both ends are connected and not cracked or brittle. you can spray cleaner around them and see if it changes the idle If you don't find your leak, you have an idle air control valve,it's round, about 3" long, w/electrical plug on 1 end and mounted to intake manifold w/2 8mm bolts. you should be able to find a new one at a NAPA store. Hope this helps you. Cliff
#46 of 54 Engine revs & doesn't kick in when hitting higher mph by vermillionx Sep 08, 2009 (12:17 pm)
Hello I have an AT 2001 Ford Focus, never had problems with it before but shortly after stopping for some gas when I got on the highway and got it up to 55mph and turned on cruise control, its like it wouldn't kick into gear and when I would put on the gas the mph would only rev the engine and the mph would decrease. I pulled over and noticed the check engine light was on.... I had to get off the highway so I tryed starting it and I was able to pick up speed very slowly as it would shift to higher mph, its only when I press on the gas harder that it does it again (revs and reduces mph until the car is stopped) Please let me know what you guys think happened? Did I get bad gas? Did something go out?
#47 of 54 vacum hose by razz44 Sep 08, 2009 (1:20 pm)
check the vacum hose on the inside on the side of the engine its hard to see but u have to look hard to see it u may have a hole in the vacum hose its right below the carb below 3 other hoses hope it makes sense because thats what is wrong with mine i found it over the weekend but its hard to fix because its so hard to get to
#48 of 54 trans by oldfordmech Sep 08, 2009 (1:31 pm)
Get it into a known good reoair shop, they should have a (GOOD) computer code reader,and tell you why you ck eng light is on. Be sure to check your trans fluid level and the color and smell of fluid, it should be pink or lt red on some white paper, it should not smell burnt or nasty. If it is brown or smells bad, it's too late and it's tlme to pay the piper, If it's red and smells ok, then you may just need a switch or sensor. Hope this helps, Cliff
#49 of 54 2003 2.3L Vibration by mel09nie Oct 06, 2009 (12:21 pm)
My 2003 2.3L Focus, manual transmission, has begun to vibrate and bog a bit when accelerating through the gears. The vibration is worst in 1st and 2nd gear but is apparent in all gears now. There is no check engine light nor does anything else do anything out of the ordinary. Basically I have just lost some of the zip. I have read some other posts and maybe it is a motor mount issue? It currently has just over 100,000 miles. I have taken it in and the mechanics say nothing is wrong. imagine that. Help?
#50 of 54 vibration by razz44 Oct 06, 2009 (1:08 pm)
could be motor mount and could be the transmission,change the fluid and check mounts on the motor
#51 of 54 vib by oldfordmech Oct 06, 2009 (6:31 pm)
Motor mounts could well be your vib, but they will not cause you to loose power. are you sure you don't have an eng miss ?
#52 of 54 Focus timing and serpentine belts... by 0311vn Oct 12, 2009 (10:15 am)
My 01 Focus has 135K miles on it and I have never changed the timing or serpentine belts. The Focus maintenance schedule states 120K miles for changing the timing belt.   My questions are: should the serpentine belt be changed with the timing belt as a preventive maintenance thing. Also, I'm told the water pump is not driven by the timing belt on a Focus as it is with other four cylinder engines. Should the water pump be changed with a timing belt change to avoid labor expenses to get at it later on? Replies to this message: dcalix (Oct 13, 2009 7:04 pm)

Replying to: 0311vn (Oct 12, 2009 10:15 am) you dont have to replace the water pump at the timing belt replacement it right next to the timing cover but if you want to do pm the car it would be wise to change it and the belts while there in there cause you have to lower motor to get to the timing belt
#54 of 54 water pump by oldfordmech Oct 14, 2009 (11:18 am)
You don't have to repl the water pump at the timing belt replacement but, This IS the time to do it. You will never be any closer. If you have high miles, this will be money well spent.
