2000 Ford Escort Engine Performance

Have you checked for vacuum leaks?

well i found the problem to the potholes...it was a loose wire...but i still have the problem with the boost calibration fault and the first gear problem..i have changed the spark plugs and the wires. and the coil and its still acing up...what does the vacuum leaks have to deal with these problems...

I was questioning the rough idle. Does the vehicle have a turbo? What is the car doing now?

nope my car doesnt have a boost...not that i know abouit...it has a rough idle and also when i try to accelerate i kind of hesitates to change from first gear to the other gear...its an automatic...

I still say there is a vacuum leak. If the check engine light was on, then I would say it is electrical / sensor.

the problem is that i dont know where the vacuum leak is...and the check engine light is not on..

I understand. THey are hard to find. The best I can tell you is to open the hood and start looking. Sometimes with the engine running, you will hear a hissing sound.

Many mechanics will spray the vacuum hoses and around the intake with carb cleaner or starting fluid. If there is a leak, the engine will rev. The only concern is the chance of fire. If the spray hits an area that is hot enough, it will cause a fire, so you have to be careful and keep a fire extinguisher near by that is designed to put out grease / oil / fuel fires.

I know it doesn't sound fun, but that is what most do.

yeah its hard to find..but i can hear the hissing noise. my dad was waiting for the check engine light to turn on. does it turn on with this problem?. it still has warranty i was wondering if the ford agency can find this problem if i take it to them??? if i cant find it..

The light could under certain conditions. However, if you hear a hissing sound, that is half the battle. With the engine cold, start it and spray some carb cleaner in the area of the noise. If the engine revs up, you found the leak. It is just a matter of locating the specific hose.

NOTE: Carb cleaner is flamable. Be careful when doing this. If could cause a fire. Make sure to have a fire extinguisher near by for oil fires and avoid spraying directly onto extremely hot engine parts such as an exhaust manifold.

Let me know what you find. And yes, I feel the dealer could find the problem.
