SOURCE: The engine in my 1999 escort has a problem. When

Check that your O2 sensor is ok. Has the engine thrown a code? Does your check engine light work?
You can check the MAF or I guess it might still be MAP in that engine but also check your exhaust back pressure to make sure the catalytic converter isn't plugging up.

Battery light on lightly


Check the alternator belt tension it ok . Then With the engine running at a fast idle check the voltage at the battery terminals , 14 to 15 volts ok . 12 volts or below the alternator or voltage regulator is at fault.

Idling problem


stalls.

your car has no year? and if working engine,? what engine? option

you start the cold engine/
can you keep it running, with a fast right foot action?
starts after 5min, then runs perfect all day???????

my guess, is one more missed tune up.

After starting my 98 metro 1 liter the idle increases in less than a few minutes until the engine is racing so fast I have to shut it down, help?


Generally speaking, the only way for the idle speed to increase is if extra air is getting past the throttle plate.
So that could include the throttle plate sticking open, the idle air control valve not closing, or a vac leak somewhere such as a hose or gasket.
If you can cover the throttle body with something and the engine still runs at a high speed there is a large vac leak somewhere.

I have a 2002 PT Cruiser. On a cold start it starts on fast idle which is excessively fast. It is actually unsafe to put the car in drive. It will stay on fast idle for 5 minutes before dropping, but then...


code p 1193 refers to inlet air temp sensor problem --circuit high
a faulty ambient air temperature sensor or barometric pressure sensor will cause this effect as the idle control in the ECM is not getting correct temperature readings to set idle speed

IDLES FAST WHEN STARTED, FOR 5 MINUTES THEN DROPS


It's the choke doing tis job. It reduces the amount of air to the engine to help it start/warm up. As the engine reaches a good operating temp it will drop the RPM's. Some times they do get stuck, so some cleaner wouldn't hurt. Spray it into the throttle body while the engine is running. Also the O2 sensor could be bad.

Idles to fast


Sounds like a vaccum leak at the throttle body or the intake. check for loose lines hissing with the motor running. Had a brake booster line come loose on my 92 and it ran at about 3000 rpms.

PVC valve is not metering air correctly, it will appear ok shaking it but looses it ability to maintain proper position causing a medium to gross vacuum leak.
