91 Camry - Extremely Rough Idle
Hey, I've had my car for about a year now and it has progressively been getting worse. It's not like the other cases I've read about the engine idle being rough after awhile- because it's only when I first start up the car/when it's cold. As soon as it's heated up and running for a while, the car runs perfectly. Also while the engine is running rough- the check engine light is on. It turns off as soon as the it's heated up.
I've had friends tell me they think it could be the cold fuel injector (whatever that is), the alternator, the wimpy battery, the starter (which I've replace)
I was just looking online for some more expert opinion or someone with similar problems- I'm a bit of a noob so any help is appreciated- Thanks!
