The idle jumps when engine is cold from 1000 to 2500 rpms and starts really rough requires pushin gas petal to start

Being efi (electronic fuel injection) the idle should be higher when starting off cold...in the older days, you used to use a choke, a handheld lever that you pulled out to shut off the air to result in a rich mixture...due to cold air there is alot of oxygen molecules, so a choke increases the fuewl mixture to compensate aiming for that 14.7:1 air to fuel mixture ratio


BUT it should not be that high, what is happening is that is dumping too much fuel in and you are having to go WOT (wide open throttle) to prevent a "flooded" condition..

Why ???? Well, it could be a faulty air flow sensor, a faulty or out of adjustment idle control, bad fuel, bad air filter, fuel filter, fuel injectors bad....etc etc

So, more info is required to solve it......when was the car last serviced, and does it only occur when cold, or do you notice that it is hard to start when hot as well.
