#70 of 126 2003 focus idle problems
Apr 24, 2010 (3:21 pm)
i just put another engine in my 2003 focus, it has the 2.0 sohc engine. the engine is used but has low miles on it. i got it running but the idle is going up and down, and it's idleing really high. i also noticed that the exhaust coming out of the tail pipe is very, very hot. it burns my hands to hold it ther for a few seconds. any ideas what it might be?..thanks.

I THINK YOU HAVE A VACCUMN LEAK. The surge is caused by the computer, the O2 sensor send a lean signal to computer which tell the fuel sys to get busy, fuel sys puts in too much fuel and the O2 sensor sends a rich slngle to computer and we do it all over again.
Take a butane torch, do NOT lite it, turn it on and go around all intake ports at cyl head. also run it around all vuc.ports. If you the eng smooth out, you have than found your vac leak.
stay in touch
#72 of 126 Car jerks back and forth, not enough power 2000 ford focus
Aug 01, 2010 (10:43 pm)
Hello, I just moved to a new city, and low and behold, my 5 speed 2000 ford focus car starts having problems and breaks down. For about a whole month my car was sitting on the road not able to start, or even hardly turn over. when it did start, it ran extremely poorly and the engine shook like CRAZY and would sometime stall. It leaked all of the anti freeze out, not from a hose, but anyways,. it has not over heated although it does seem to get very hot. The wierd thing is that, it only leaks sometimes, sometimes alot, and sometimes it wont leak for a week. we went outside to start the car again after a month and it started like new, drove around without any problems other then a little leak, and the engine did not shake one bit!!! Just the other day, the car started to be jerking back and forth when i would try to drive it. The car would start fine, but then when i went to drive it, it would jerk angrily back and forth at times when i shifted gears or tried to accelerate. At times it actually would feel like it is going to stall. also, at times i would put the pedal down to the floor and it would hardly move like it has no power, and then all the sudden BAM it would jerk you and you would go realy fast, very inconsistent speed. the cars engine makes a little hissing noise you can hear at times, and the idling goes from below one to one and a half on its own just up down up down... i know this is alooooot of things all at once but is there anyone who knows what this might be? I dont know to many people in this city so i would really appreciate any suggestions!!!! thank you..
#73 of 126 2000-2003 Ford Focus Cylinder Problems?
Aug 13, 2010 (7:19 am)
Anybody hear about cylinder malfunctions in these Focuses? I just had a dealer tell me he had to rplace cylinders on a 2000 because it was running on just 3 cylinders. Is this a common problem? Once they are all replaced can I assume the car will be reliable? Thanks

Everybody knows Ford put cheap ignition switches into the early Focuses. Can they be replaced with better made ones or do you have to replace them only with Ford's stuff? Thanks
#75 of 126 intermitant misfiring and stalling
Sep 18, 2010 (2:07 am)
My daughter has a Focus 1991 Zetec1.6 estate. When petrol tank is fulll runs ok. As soon as gets to 1/4 full it missfires slows down engine cuts, jerks starts again , and continues in this way and has often stopped altogrther. Has been in the garage several times but they dont seem to know what to do. Fuel pump ok. Now say they will give a diagnostic check. If no go then will drain the tank and clean it out. They suggested that the tank be well topped up, but with 2 kids to cart around she cant forever be pulling into a station to fill up.
Has anyone any ideas on this one please?

#78 of 126 Engine Problems
Jan 19, 2011 (5:20 pm)
My 2003 Focus has no power what so ever. The car jerks back and forth like it wants to stall. From a stop, it takes me about a quater mile to get up to 30 miles per hour. The check engine light was on, but after changing the O2 sensors is went off. Drove it home from the shop and the check enghine light started flashing. Just had new plugs, wires, coil pack, O2 sensors, and filters changed and it did not help. The mechanic just called and said, "come pick it up. We cant figure out whats wrong with it". Now I have to take it to a Ford dealer that wants to charge me $94 per hour to diagnose the problem. Anyone have any ideas that do not include pushing it off a cliff?

Try taking your exhaust pipe loose at the exhaust manifold, just have it very loose but do not
take it off. Take it for a ride & see if you now have better power, if so, you have a plugged catalic converter. If that does not fix it, check your timing belt ( if you have 1. not sure ) if you
do, line up the timing mark on the crank pully with the notch on the ft cover, remove belt cover and look for timing mark on cam sprocket, it should be at 12 noon, if it's at the bottom, rotate the crank 360 * and recheck. If belt is worn it may have jumped a tooth or 2. If you have a timing chain,under the valve cover, disregard the belt info.
Let me know what you find
