problem #2

Jul 012001

Focus ZX3 2.0L

  • Manual transmission
  • 6,000 miles


Here are common causes of your complaint.

Radiator Fluid or water can get trapped on the ceramic area of the spark plug causing a miss-fire. All that is needed is to remove one plug at a time and dry the crevice where the spark plug seats, then spray the porcelain area with a small amount of WD-40, and a very small amount on the plug connection.

Check your battery connection! The focus hates dirty battery connections, take them off, clean them up and put it back together. One important note: DO NOT USE METAL BRUSHES on your battery. Dissimilar metals cause corrosion. Use a brass brush, or a rough scrubbing pad from the kitchen. I don't use coke, just a little water and baking soda is all you need. Then rinse. I know, there will be a lot of people who roll their eyes, but bad battery connections will cause a focus to run really bad, its very hard on the computer.

Have your technician check to see if you need a new gas pump/filter. Ford had a recall campaign on the gas pump, so you can get it changed for free.

Next Check the hose on the throttle body, top hoses for leaks, however reaching behind the throttle body and checking this hose the engine note immediately changed. They have superseded the old hose due to it being a known common problem. The hose required is ford part number 10762884 ,tube/crank vent

Then have them check the Check the TPS (Throttle Position Sensor) which is bolted to the throttle housing. They will need to perform these checks: Switch ignition on and with a multi meter on DC volts check the center wire it should show a reading between 0.67-0.7volts if any different then the TPS needs adjustment.

problem #1

(reported on)


  • Automatic transmission
  • 95,000 miles

I'll be driving along and it idles at about 2 on the RPM thingy. and when I try and stop it's like the idle keeps pushing me forward. The Idle will reduce once i am driving, but sometimes it won't before i have to stop and park and as soon as i put it in park the RPM goes up to past four. After a stop light i don't even have to step on the gas and it will get up to 35 miles per hour when it is idling like this. I know that I will need to get the transmission fluid changed soon. Could that be the problem why this is happening because i need to get that changed?
