I've had my 93 integra Gsr for almost 2 years now and I honestly can't remeber when the problems started but they've been around for quite some time. There seems to be mysterious problems that always come and go and its hard to predict them some times. sometimes the car runs smooth and will be fun to drive and then other times it feels sluggish. If I drive it for too long sometimes, while Im driving, the car will feel like if its being held back then not and then again. then when I stop the idle rpm will be at 200 then I stop at another place and the rpm will be at 600 then 800 then back to 200 then to near zero and it gets frustrating. and then sometimes the car doesn't want to turn on and then I get a check engine light and it goes away before I can even diagnose the problem. It has over heated twice because all the water came out and then now no water leaks and I HAVEN"T FIXED ANYTHING!! I have absolutely no idea what the hell is going on. The engine was rebuild a while a go and before it was it had the same problems. could it be an electrical problem because if you were to look under the hood you would think that it is in the best of all conditions. oh yeah and sometimes the airconditioning fan will turn on and off even with the car turned off.
