This sounds to me like one of the sensors could be giving you a problem. The areas I would look at are the throttle cable, and check the sensor connections one may be loose, with the choke light coming on that would point to the throttle cable or the idle. Check out the articles at Auto Tap they are pretty good on this area. There are several DIY aticles if you go back to the homepage, I put the link for the Check Engine Light below
