I have quite an odd problem with my '81 automatic. After driving it for about 20 miles in light traffic it gets a very rough, high sort of idle. It has been doing this for quite sometime (since summer), but it was very rough today; allow me to elaborate. When I slow down from normal driving speed (45mph) to a stoplight the whole car seems to shake, and I notice that the rpm is about 750, in gear, and almost 1000 rpm in neutral! Wwhen I start to move again it smoothes out just fine, but you can tell that it wants to keep moving all the time, example- almost like the throttle is stuck open a tiny bit... when cruising the only difference i notice is it doesnt loose speed as fast.. it seems like the engine is still pulling... like im tapping the pedal a tiny bit, though im not. This problem goes away after the car has been sitting overnight, regardless if the fast idle comes on because of cooler temperatures. Could all this be related to my tcc selenoid problem in my tranny? It started around the same time... why does it happen only after I drive it for a while? I dont think I could fix this problem myself since my mechanical inclination of cars is low, and I only have basic hand tools, but I would like to know if I should bring it in to my vette mechanic or just live with the problem? Besides the shaking at idle there is no problem, and I dont mind the shaking that much, just worries me.. thanks for everyones help in advance and sorry for the long post.
