#78 of 120 Engine Problems
Jan 19, 2011 (6:20 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

#82 of 120 problems with 2000 focus

My 2000 focus spits and sputters, jerks and doesn't have any power, engine light flashes, and i smell antifreeze, but all this only happens when it gets wet, otherwise it works fine. i've already gotten a new catalytic converter, O2 sensor, some sort of throttle part, the plugs and wires are good, don't know what it could be. any suggestions?

#84 of 120 Trouble with 2001 focus zx3
May 15, 2011 (2:00 pm)
Help! We recently bought a 2001 focus zx3. Bought it as is, and 2 days later the check engine light comes on. It always idles high. If you are doing 60 down the highway and shift it into neutral, the tach goes over 4000. The code said it was the IAC. I replaced it, but nothing changed. Had meineke turn the check engine light off, next day it came back on. They looked it over, said either the part I put on is bad and I should put on another, or I should take it to the dealer to diagnose. He thinks it may need a new computer.
You fine people seem to have had many of these problems, any ideas of what I can do next without having to spend the money at the dealer? I have already changed plugs and wires, cant find a vacumn leak.

The IAC is the idle air control valve, it is a can shaped about 3" long with a diamond shape base, held on with 2 8mm bolts.and a wireing loom at the other end. Is this what you replaced.? and where did you get it.?
Something else you might try. taking your throttle posistion sensor, loose from the air intake
tube and see if the idle comes down.
