car: '86 GL-10 Wagon/5 speed/fuel injected.
The car is idling really high when cold. it has been up to 2300rpm. i know a high idle when cold isn't really uncommon but this seems crazy. Also, a few times, when sitting at a light in neutral, the car will rev up and down as high as 2500rpm down to around 1000rpm. And it won't stop until I put it into first and drive.
I've done some searching on the forum and mostly found vac leaks or the coolant temperature sensor is going. I'm going to have some time to work on this on wednesday so I was wondering if anybody has any other thoughts?
The only thing I've done to the car recently is an oil change and I put in a new fuel filter.
Any input is greatly appreciated. Thanks.
