I have an 86 Honda that when you start it cold, it will start at around 2k RPM, then hover around there, then it will shoot to around 4/5k and stay there. We used to ahve to tap the pedal to get the RPMs to settle, but now it wont do that. When i look at the choke, at start up it is closed. After turning the engine over, it opened to about 1/3rd. I watched it for about ten minutes and it does not open any further, even when the idle goes to 5k. I have to either turn off the engine and let it violently shake and diesel, or if i click the ignition to off very quickly a few times, it brings it down to around 2k where i can turn it off. I don't know TOO much about cars, but my girlfriend has written the car off as helpless so i seem to have free reign over it. Any suggestions? I don't know where any of the parts i've read most about are, like the Idle screw, or the Fast idle thermal valve. Pics would be great. Thank you in advance for anyone who can help!
