I had the same problem. Solved it with a new battery. Had the old one tested and it was bad.

2005 kia amanti cranks then goes dead. No lights on. Some days when cold cranks and runs up to 5k rpm. This morning wouldn't run unless I keep my foot on the gas and brake then it runs fine.


The first thing I would do is check the battery terminals. If they look clean then try twisting the terminal. If you can move it it is loose! With an interruption of power to the Electronic Control Module (the computer that runs your engine) it sometimes has to relearn how to keep the engine running especially in extreme temperatures. That's why you had to keep your foot on the gas. Once the engine warms up it should begin to operate normally.

Need codes, because the engine and transmission will both cause "reduced power".

Throttle position sensor problems


reduced engine power has to do with the electronic throttle control or drive by wire . All electronic wires under the dash on the gas pedal , electric motor on the throttle body . DTC'S - diagnostic trouble codes stored in the computer . Take it to the dealer .

Yes the throttle and pedal sensor can do this, but doesnt reduce power,Your cam postion sensor reduces power and if you thing it gives a engine code,it doesnt have to,This sensor is back up by the crank position sensor,The location of this sensor is in the back of the cylinder head

My truck wont start unless i prime the carborator first, then it wont stay running unless i rev it high just before i put it in gear, or im accellerating...


To start with, you have a throttle body instead of a carburetor.
On that throttle body is a component called an air control valve.
That valve is how the computer controls the idle speed. It should open and close the air flow into the intake manifold as needed.
Is the check engine light on when you are driving ? Have you checked the fuel pressure ?

Service Stabilitrak-Reduced Engine Power


the engine light is a generic fault indicator in your car to point out something is not quite right with the engine, having a loss of power as well is also known in some areas as Limp Mode or Safety Mode. it means the car is restricting the power it gives to ensure no damage it done to the engine.

the only certain way to find out what is wrong is to take it to a garage that has diagnostics equipment that can read the fault codes from the vechicles ECU (the fault codes will be the reason the light on the dash has come on as its reporting a fault somewhere)..

your mechanic should be able to tell you what is wrong with the engine from that and give you a more accurate cost at fixing it.

Reduced engine power


hi there my name is don i will try to help you on this
when your reduced engine light comes on that means there is a active fault code in one of the sensors that is cusing this
you will have to get it scanned or retreive the codes from the dash

once you shut it off and turn it back on it temporarly resets until the diagnostics go through it again and it will reduce the power to the engine
it could be something simple like a gas cap or tire pressure but you will have to get it scanned to find out
thanks
